Introduction
Enviro Data is a data management
system for capturing, managing and displaying site analytical and other
related data. It is an excellent learning tool for site environmental data
management concepts. This document describes the Enviro
Data system and how to use it. It describes how to
create and attach to a database, select data, create lists, reports, maps
and graphs, and how to create subset data sets which can be taken or sent
to remote locations, or used locally for performance reasons. It also
describes how to use the keyboard shortcuts available in Microsoft Windows
and Microsoft Access.
Geotech Computer Systems, Inc. (Geotech) created Enviro
Data to suit our clients’ current and future
needs. The purpose of this software is to provide a way to electronically
import data from the field, analytical laboratories and consultants,
manually input data, edit and otherwise manipulate the data, and create a
variety of reports and other displays. The software can be installed on
individual Users' computers, and the database can run on a User’s
computer or on a server computer. System Administrators, Data
Administrators, other Staff members, and project managers should be
trained on the theory behind the system, issues related to computerized
data management, and how to operate the system and customize and enhance
it as their needs change. The system also provides the capability to
create subsets of data that are then transmitted to other locations.
The data model (data elements to be stored) for Enviro
Data was developed jointly by Geotech, our clients’
labs and contractors, and our clients. Enviro
Data is based on the client-server model of
networked computing. In this model, software operating on desktop
computers communicates with a database program running on a server
computer across a network. A computer (the client) resides on the
desk of each User. This client computer is connected to a computer shared
by many Users (the server) via network hardware and cabling. The
client computer, or front-end, runs the software that provides the
user interface and any local processing for the client-server system. The
server provides three primary services to the clients: database
services, file services and print services. One computer can
provide these services, or the duties of each service can be split among
several machines. Enviro Data
uses mostly database services, and the services are provided by a database
server, which runs the back-end or server-side component of the
data management system. Enviro Data
uses Microsoft Access for the client (front-end) and Microsoft SQLServer
or Oracle for the server (back-end).
The Access user interface for this system contains the
menus, forms, reports and program modules to operate the system. With this
program, database Users and Administrators can import, manipulate and
retrieve site analytical data. For consistency and quality, Data
Administrators should do all data importing, editing, and other
miscellaneous administrative duties. Users should only be able to view
data, not edit it.
There are two types of administration required for the
current Enviro Data
System. These are System Administration and Data Administration. An
individual can provide more than one administrative function.
A System Administrator manages the SQLServer database.
Often this task is performed by an Information Services (IS) staff member.
Assistance can be provided from Geotech as requested by our clients. The
System Administrator is responsible for general maintenance of the
computer system, administration of Users, database maintenance and system
backup. Data Administrators are responsible for maintenance of the data.
Staff designated as Data Administrators are responsible for data import,
editing and working with project managers on data review. Data importing
can be done one of two ways, electronic or manual. The system provides
automated import for analytical laboratory data submitted in one of the
approved electronic data formats.

Description of the problem:
There is no reason for the redundant fields, either in
the tables or the relationships. The fields Sample Date, Sample Type,
Matrix, Beginning Depth and Ending Depth need only be in the
Groundwater/Soil Sample table and not in Soil Sample Results, Groundwater
General Chemistry Results, QA/QC Results, and Soil Gas Data Results. (It
might also be possible to combine these four tables into one, but we can’t
tell without seeing whether the other fields are the same or different.)

Enviro Data
Tutorial
This tutorial is intended to give you, the Enviro
Data User or Data Administrator, an overview of Enviro
Data. It can be used as a hands-on guide to working
with this program, and to learn the concepts of site environmental data
management. This section provides basic instructions on opening the Enviro
Data program and associated databases, selecting
data from the analytic data tables, and presenting the information in
lists, reports, graphs, and maps. It then proceeds to data administration
functions such as importing and editing data. Section 4 of this manual
provides a detailed reference for the Enviro
Data functions outlined in this section, along with
many others, and you should refer there for more information.
Note: In this section and in subsequent sections of
this document, certain typefaces are used to reference different objects
in the system. These typefaces are listed in the following table: |

underlined where possible (i.e. File/Print or Tools/Copy).
Accelerator keys can be used by pressing the Alt key on the keyboard
together with the underlined letter to execute the desired menu choice.
Buttons or options without accelerator keys underlined are referred to
with the entire word underlined (i.e. Open or OK buttons). |
|
Using
Enviro
Data
Once you have installed Enviro
Data, you can follow the steps in this section to
start to learn about how the program operates and what it can do for you.
Opening Enviro
Data
Opening the Enviro
Data program involves starting Microsoft Access and
opening the program database file. This section describes how to do that,
and covers attaching to the settings and data databases if necessary.
- Open the
Enviro Data
application by double clicking on the Enviro
Data icon on your desktop. You can also open Enviro
Data by clicking on the Access icon. If you start
Access from the Access icon, select Open Existing Database
and then choose EnvDProg.mdb. Click Open.
This file contains the Enviro Data
program code. The location of this file is determined by the choices you
made during the installation process, or will be supplied by your System
Administrator. Double clicking on the Enviro
Data icon will open EnvDProg.mdb for you
automatically. If you are attaching to SQLServer, the LOG ON
box appears. Type in your username and password to continue.
The first time you open Enviro Data,
if you have installed a new version, or if the data files have been moved,
you may need to attach two databases to the program, a settings database
and a data database file. If the program cannot locate the setting
database it prompts you to attach to a settings file by opening the ATTACH
SETTINGS form, shown in Figure 1.
|
|

Figure 1 - Attach Settings
dialog box of ATTACH DATABASE |
- To attach the settings file, Settings.mdb, you can either click on
the Select Settings File button and select the settings
file using the OPEN dialog box, or you can type the path
and filename directly into the ATTACH SETTINGS form and
click the Attach Settings button. The Settings.mdb file
should be located on the client computer or in a User folder on the
server. If you are unable to locate the Settings.mdb file, contact
Geotech Computer Systems or your System Administrator. This step can
be skipped if the ATTACH SETTINGS form does not appear.
After selecting the settings file, the ATTACH
DATABASE form, which is shown in Figure 2, may appear. The
database attachment process is shown below.
Attach Database
With Enviro Data
you can store all of your data in one big database, or store particular
sites or groups of sites in individual databases. To use a particular
database, you "attach" to that database. This section describes
how to do that.
- To attach to an Access database file (which must be in
Enviro
Data format), click on Attach Database
on the MAIN MENU. The ATTACH DATABASE form,
shown in Figure 2, will be displayed. Then click on Select Subset
File and select the database using the OPEN dialog
box or type in the path and file name and click on Attach Subset.
To use the tutorial database, use "EnvDData.mdb".
|
Figure 2 - ATTACH
DATABASE dialog box |
|
To attach to the Enviro
Data database in SQLServer, click on the Select
Server combo box and select the appropriate database. Enter the
User name and password assigned by the System Administrator to log into
the database. After you attach to an Access or server database, the Enviro
Data MAIN MENU appears on your screen. A copy of this
screen is shown in Figure 3. At this point you are attached and ready to
go on with using Enviro Data. |
|
Overview of the Data Model
After opening the program and a data database, you
might want to learn a little about the database design. This section will
show you how to get an overview of the database using the RELATIONSHIPS
window, and how to view the structure of a table to see the data that it
contains. Then we will move on to the features of the software.
- First we will look at the RELATIONSHIPS window. On the
Access main menu bar, click on Tools/Relationships. The RELATIONSHIPS
window will be displayed. The boxes represent the tables in the
database. The line at the top of the box shows the name of the table.
The lines in the lower part of the box show the names of the fields in
the table. The lines between the boxes show the relationships between
the tables. Close the RELATIONSHIPS window when you have
finished looking at it.
- Next we will look at the structure of a data table. Open the DATABASE
window by pressing function key F11. Choose a table such as Sites,
and click on Design. You will be warned that you will
not be able to modify the structure. Click on Yes to
proceed. The three columns show the field name, data type, and a
description of the data that the field is to contain. If you click on
a field, the lower part of the screen shows more details about the
field. Click on File/Close to close the table design
window. Minimize (but don’t close) the DATABASE window
by clicking on the minimize button (
) in the
upper right corner.
Main Menu
The MAIN MENU form takes you to the major
features of the program. This form is shown in Figure 3. |
Figure 3 - MAIN MENU
of Enviro Data |
|
The features shown on the MAIN MENU will be
described in the next section. Note that if you are a User and not a Data
administrator, some of the buttons, and thus some of the program
functions, will not be available to you. |
|
Above the MAIN MENU, you will see the Enviro
Data TOUR form. This tour is supplied
to help walk you through the main features of Enviro
Data, and appears when the program is first opened.
This written tutorial was created for the beginning user to learn the
fundamental processes and functions of Enviro
Data by reading along within the manual and
following on screen. It is built to be used while attached to the tutorial
database, EnvDData.mdb. The Enviro Data
TOUR was created to offer any user the option to learn Enviro
Data on-screen, with or without following along in
the Tutorial. If you close Enviro Data anytime during the tour, it will
remember where you left off, and start in the same place upon re-opening.
Or you can close the tour form by clicking on the ‘x’ in the upper
right hand corner of the form and continue using the program. It will
reappear the next time you open the program. To close the tour for good,
just select the End Tour button and choose Yes.
Maintain Database
Before we dig into working with the data, let’s first
look at some features of the software that help you work with your data.
Some of these features are accessible from the MAINTAIN DATABASE
form.
- Click on Maintain Database on the MAIN MENU.
The MAINTAIN DATABASE form will be displayed. We will
look at some of the options on this form.
Lookups Report
The program contains a report that shows you the data
in the tables that provide code expansions and other supporting
information for working with the data in the main data tables.
- Click on Lookups Report on the MAINTAIN DATABASE
form. The program will display the LOOKUPS REPORT.
- To zoom out to see the whole page, click in the middle of the
report. Use the record selectors along the bottom of the report window
to move to other pages.
- Close the LOOKUPS REPORT.
Activity Report
The software maintains a record of changes made to the
data. Later we will see the screen that gathers this data. Now we will
look at selecting and reporting this data.
- Click on Activity Report on the MAINTAIN
DATABASE form. The program will display the ACTIVITY
REPORT selection screen.
- Enter some selection criteria to select specific activities to
report. Select "drdave" for administrator from the drop down
list and select "Rad Industries" for the Site. Then click on
Display Report. This report shows activities that were
performed which may have resulted in changes to the data in the
database.
- Close the ACTIVITY LOG and the ACTIVITY REPORT
selection screen.
Database Statistics
Sometimes it’s useful to look at an overview of the
data of the database to see what data is present. Data about what data is
there is sometimes called "metadata". |
- Click on Database Statistics on the MAINTAIN
DATABASE form. The program will display the DATABASE
STATISTICS selection screen.
- Leave "All Sites" selected. Then click on Display
Report. The first page of the report shows general information
on each site. The remaining pages show more detailed overview
information on each site and the stations and samples for that site.
- Close the DATABASE STATISTICS REPORT and the selection
screen.
Samples Due
The program can help you track which stations have
samples due in the near future. It is based on the most recent sample for
each station, and the sampling interval defined in the Stations
table.
- Click on Samples Due on the MAINTAIN DATABASE
form. The program will display the SAMPLES DUE REPORT.
This report shows stations for which sampling is overdue.
- Close the SAMPLES DUE REPORT. Close the MAINTAIN
DATABASE form.
Analytic Data
The bulk of the activities involved in working with
data in Enviro Data
are accessed through the SELECT DATA form. The following
sections cover many aspects of working with this form.
Selecting Data
When you are working with a large database, you can
improve performance by keeping your selection set small. If you are
working with only one site, for example, you should choose the site before
you move on to working with stations, and so on. This example will follow
this approach.
- To start working with data, first select a site to retrieve. You
should select a site from the MAIN MENU using the
dropdown box in the Current Site selection field. You
can work with more than one site at a time, but if you are working
with one it is better to select it on the MAIN MENU
before opening the SELECT DATA form to speed up
operation. Then click on the Analytic Data button in the
MAIN MENU and the SELECT DATA form
appears. This screen is divided into 3 sections: the Filter Criteria
Boxes, the Status Bar, and the Action Menus.
|
 |
Figure 4 - SELECT DATA form
|
|
Sites
The Filter Criteria Boxes display a set of selection criteria on the
screen as the Sites, Stations,
Samples, and Analyses option
buttons are selected. Select the Sites option
button in the Filter Criteria Boxes then click on Update.
Notice the Number of Records listed on the Status Bar. This
number changes depending on the option selected (e.g. Number of Sites.).
In the Sites Filter Criteria Box, click on the arrow to
the right of Site selection field. Select "Rad
Industries" from the list, and click List (under Output
in the Action Menus) to see the new data set. We’ll look in more
detail at the features of the list window later. After you have looked
at it, close the list window.
Stations
- Select the Stations button in the Filter Criteria Boxes,
and the Stations selection criteria filters appear. Select
various criteria and click on Update. Notice the change in
the number of records listed on the Status Bar which meet the criteria.
In the Stations Filter Criteria Box, click on the arrow to
the right of Type selection field. Select "Monitoring
well" from the list, and click List (under Output
in the Action Menus) to see the new data set. If the selection
criteria query finds no records to fulfill the requirements, a message
box appears stating that "No records were returned from the
criteria you specified." Stations displayed are limited to the
selected site. Close the list window.
Samples
- Select the Samples button in the Filter Criteria Boxes
and click on List to see the new data set. In this
case, samples displayed are limited to monitoring wells at the selected
site. The scroll bars and arrows may be used to view other areas of the
table that go beyond the limits of the monitor screen. Close the list
window.
|
- Samples results can be limited by entering criteria in any or all of
the Filter Criteria Boxes listed under samples. Select "Water"
from the (Sample) Matrix dropdown list. Click on List.
The samples retrieved are limited to water samples for the selected
stations, and the selected site. Close the list window.
Analyses
- Select the Analyses button in the Filter Criteria
Boxes on the upper right of the screen. Select a parameter, such as "Sulfate",
from the Param. option. You can click in the field and type in the
first few letters of the name, and the correct one should appear. The
parameter dropdown list comes from the Parameters table. It is
not restricted by the selections already made. Click on Update
to see the number of analyses.
- Results can be limited by entering criteria for other data types.
Click in the value field and type in a value, such as "1000",
and click on Update. Only analyses with that value are
reported. Put a ‘<’ sign in front of the value, and click on Update.
Note the additional records returned.
- To view a report of the selected analyses, click on Output
then Report and Preview/Print. The report
option will be discussed in more detail later. When you are done,
close the report window. Clear the value field by clicking on the ‘-‘
to the right and click on update. Notice the number of records listed
on the Status Bar.
Query Basics
The SELECT DATA form is a very powerful
and flexible way to work with your data. This form is described in detail
in the reference section of this software manual. This section will
highlight a few of the capabilities of this form.
Auto Expansion
Some of the fields can expand automatically to allow
you to type in a minimum of characters, and yet still perform the query as
you wish.
- Click on Reset, and then select "Refining
Inc." as the site.
- Click on the Samples radiobutton. Enter "86"
in the S.Date field. Then click on Update
to count the records. Note that the form has expanded the year into a
full date range, and then used that date range for your query. (There
doesn’t happen to be any data for that year for that site.)
- Try entering "last year" for the sample date and counting
the results.
Modifiers
The selection screen allows you to use
"modifiers" to change the interpretation of data that you enter
in the criteria boxes. These modifiers are described in detail later. The
following is a brief example of this feature.
- Click on Reset and then the Analyses
radiobutton. If you have AutoUpdate enabled, you will see that a large
number of records have been selected.
- Enter "120000" for value and click on Update.
Two records are now selected, those with exactly that value.
- Now enter ">=120000" for value and click on Update.
Several more records will be added, now representing those greater
than or equal to that value.
Default Values
The program tries to make it
easy to start over from scratch with values in the selection screen which
are most likely to give you the records that you want to see.
- Click on Reset. The contents of the selection criteria
boxes will be changed to their original values, and the Sites
panel will be displayed. As you move between the different criteria
panels, the values will be set to the defaults for the form. Another
section of this document describes how to change these defaults.
Update/Auto Update
You might be tired of clicking
on Update each time you make a change. If you check the box
next to AutoUpdate, then the count will be updated
automatically each time you make a change. This option works well for
small databases, but can significantly degrade performance on large
databases, so use it with caution.
- Check the box next to AutoUpdate. Make some changes,
like switching between the Sites and Stations
radiobuttons, and choosing some data in some of the selection fields.
Note that the number of selected items changes automatically when the
box is checked.
Save/Load
You might put a significant
amount of effort into defining a selection set with the SELECT DATA
form. The software lets you save a selection set with a name for later
use.
- A set of selection options can be saved for future retrievals. Click
on Save/Load in the Action Menus and click in the Saved
Criteria box. Expand the criteria box with the
button. Choose "Sulfate Graph". Note how the software fills
in entries for you. This selection set can be edited or deleted by
clicking on Edit Saved Criteria.
Options
The software has some other options for changing how
data is displayed.
List/Range Specifiers
The selection process provides you with a method to
describe lists and ranges of data in a simple way. This is done using
"delimiters" to separate data elements in each selection field.
You can set these delimiter characters so that they don’t conflict with
characters that may be present in your data.
- First, you should clear the form and reset it to its staring state.
Click on Reset to clear any data and display the Sites
criteria box. Click on the Options tab. Note that the list
specifier is set to a comma and the range specifier is set to a colon.
- Click on the Stations radiobutton. We will select two
stations for display. Expand the Name field by clicking
on the left
button.
Type in "MW", and then click on "MW-2" to select
it from the list. Now click on the middle
button, repeating the process but selecting "MW-4". The form
has added the second station name, with a comma (the list specifier)
between the two station names. Click on Update to count
the records, and it should display two stations, because we gave it a
list of two.
- Now change the comma to a colon. Click on Update to
count the records, and it should display four stations, because we
gave it a range that includes that many.
|
|
Show SQL
Behind the scenes, Enviro
Data is taking the selections that you enter and
converting them to Structured Query Language (SQL), which is the selection
language understood by Access and other database programs. If you wish,
you can see the queries that the program is creating.
- First, you should clear the form and reset it to its starting state.
Click on Reset to clear any data and display the Sites
criteria box. Select "CO" for State to select
just the sites in that state.
- Click on the Options tab, and click on Show SQL.
The program will display the current SQL statement, as shown in Figure
5.

Figure
5 - SHOW SQL form
Click on Show SQL again to close the window.
Output
After making your selections, Enviro
Data allows you to view your data in a variety of
ways. These are accessed through the Output tab.
Tree View
If you want to quickly get to one specific result, the TREE
VIEW form is often the best way. Unlike other output options, this
display is not based on the selections that you have made, but rather
works with all of the data in your database.
- Click on the Tree View button. The TREE VIEW
form will be displayed.
- Click on the
button
to the left of "Refining Inc.". Then click on the
button to the left of "MW-14" and of the "3/16/99"
sample. Watch how the branches expand to display the data. The result
of this is shown in Figure 6.
|
|

Figure 6 - TREE VIEW
form
|
- Close the TREE VIEW form.
List
The simplest output option is the List
display. It lets you quickly look at your data, and easily move it to
other applications.
- First, click on Reset to clear any data and display
the Sites criteria box, and then select the Stations
panel. Then click on List. You will see a grid-like view
of your data.
- Highlight the Station Name column and click the right mouse
button to display a selection box. Choose Sort Ascending to
reorder the data display. Unlike Excel, you do not need to highlight
all rows/columns to reorder the table, only the ones you wish to
reorder on.
- Double click on the line between X Coord and Y Coord
to automatically set the column width to match the data. Repeat for
the line after Y Coord.
- Grab the line to the right of Datum and drag it to the left
until the column goes away.
- Click on the Station Name column. Then click and drag the
column name to the left of the Site Name. This will reorder the
columns.
- Drag across the column headers for Site Name, Station Name,
X Coord., Y Coord., and Ground so that the
columns are highlighted. Click on Edit/Copy to copy
these columns to the clipboard. Open your word processor and click on Edit/Paste.
It’s that easy to move data into your document.
- Close the list window and choose ‘No’ to the Save Changes
prompt.
Report
While the List option is a quick way to
view data, you may want a more formal, formatted report for printing. The Report
option provides this. The program comes with several standard and custom
reports, and you can add your own as well. These include Graph Reports,
Periodic Regulatory Reports, Regulatory Reports, an Analyses with
Regulatory Limits Report, a Summary Water Report, and a Well Information
Report.
Standard reports provide the most basic output for each
data level, and include: Standard Sites, Stations, Samples, and Analyses
Reports. Also, a basic Statistics Report is available at all criteria
levels.
- First, click on Reset to clear any data and display
the Sites criteria box.
- Click on Report to see the sites in report format. The
SELECT REPORT form appears. Reports for Sites
are the only options available at this point, because only the Sites
Filter Criteria Box is selected. Options for Stations, Samples,
and Analyses appear as selection criteria are added.
Select one of the reports and click on Preview/Print.
Select File, Print from the Access menu
bar, if you wish to print this report. Close the report window (Click
on
box in upper right
hand corner) to return to the SELECT DATA form.
|
|

Figure 7 - SELECT REPORT
form for Sites. |
|
Custom reports provide more specific output formats for
various uses. Custom Reports are constantly being added to the program.
Here is an example:
- Click on Reset to clear any data and click on the
radio button to display the Analyses criteria box. Enter
the following selections: Site: "Rad Industries"; Name:
"MW-1, MW-3"; Sum.Cat.: "Metals".
- Click on Report, and then "Regulatory Report by
Parameter". If you wish you can print the report, or save it in
one of several different formats for importing into other
applications.
- Close the report when you are done.
The custom reports have specific data level
requirements. That means that, depending on what criteria boxes are
displayed, you will see different custom reports. The program lets you
create your own custom reports and add them to the menu. This capability
is described in a later section.
Map
Enviro Data has a built-in
mapping feature to allow you view simple maps of your data. You can
display the data with colored circles ("bubbles") whose color is
based on the value of a parameter at that station. The cutoffs for the
colors can be entered by hand, or selected automatically based on
regulatory limits entered in the database.
- Click on the Save/Load tab and select "Radium Map".
- Click on Map. Because there can be multiple results
for each station, the program asks you to pick which value to use.
Click on Max Value.
- Enter cutoff values of 1, 10, 100, and 1000. Then click on Display
Map.
- Shift-drag with the left mouse button across some of the bubbles to
zoom in. Control-drag to pan. Click the right mouse button and select
"Reset" to zoom back out.
- Zoom in so that only a few stations are shown. Click on Show
Station Names w/ Values, and then on Draw. This
will add the station names to the values.
|
- Click on Clear, and then on Draw Stations.
This displays all of the stations for which there are map coordinates.
It will often show more stations than those displayed with Draw,
since that option only shows stations with analytic results. Close the
map when you are done.
|
Figure 8 - MAP DISPLAY form |
|
Graph
The program has an option for displaying a simple
time-sequence graph. You can display one parameter for multiple stations,
or multiple parameters for one station. The program will display a
regulatory limit if you choose a single parameter, and if one has been
defined for that parameter. It will also look at the data being retrieved,
and if the units are not consistent for the data being returned, it will
offer to use the unit conversion feature of the software to convert to
consistent units. An example graph is shown in Figure 9.
- Click on the Save/Load tab and select "Sulfate
Graph".
- Click on the Graph button. You can print the graph if
you wish. Then close the GRAPH window.
|
|

parameter with Regulatory Limit posted. |
|
Subset
The program allows you to make a database file that
contains only the data that you have selected. This may be useful when you
want to take a subset of data on the road, or you may do it for
performance reasons when the parent database is very large.
- To create a subset database from the criteria selected in the SELECT
DATA form, click on Output, then Subset.
Choose the path and directory to store the subset file. The program
database directory must contain a copy of an Access database file
called BlankDB.mdb. Type in a filename for the subset to be created,
then click on Save. Close the SELECT
DATA screen. The MAIN MENU appears. Click on the
Attach Database button to attach to the data subset you
just created. Click on the Select Subset File button and
locate the path and filename for the subset you just created. Click Open
on the OPEN FILE DIALOG form. The program attaches the
files and returns to the MAIN MENU.
- Click on Analytic Data on the MAIN MENU
to go to the SELECT DATA form. Click the Analyses
button in the Filter Criteria Boxes, and List (under Output)
to display a list of the data subset.
- Don’t forget to re-attach to your original database when you are
finished looking at the subset.
Export
The program allows you to export data in a variety of
formats for use by other programs. In this example we will export data for
use by a contouring program.
- Click on Analytic Data on the MAIN MENU
to go to the SELECT DATA form. Click on the Save/Load
tab and select "Radium Map".
- Click on Export on the Output tab. Choose
"XYZ ASCII File" and click on Next.
- As with the internal map, you need to tell the program which value
to select for each station for export. Click on Max. Value.
- Enter a file name like "Radium.dat" and click on Save.
- Use Windows Notepad or another editor to open the file to look at
the format. Close Notepad and the SELECT DATA form.
Modifying Data
The previous sections covered activities that can be
performed by all users. Some organizations provide different data access
privileges to different classes of users, based on their responsibilities
on projects. Enviro Data
supports a distinction between "Users" and "Data
Administrators", with Users having read-only privileges, while Data
Administrators can both read and write data. The following exercises
require Data Administrator privileges.

Activity
Log
Enviro Data helps you track
activities that may have resulted in changes to data in the database. This
is done through the ACTIVITY LOG form.
Filling Out the Form
The ACTIVITY LOG form appears whenever
you complete an operation that may have changed data.
- From the MAIN MENU, select Admin., then Data
Utility. Click on Stations. The STATIONS
form will be displayed.
- Close the STATIONS form by clicking on Done.
The ACTIVITY LOG form will appear.
- Describe what you did by entering something like "Looked at
Stations form but made no changes". The window will not close
until you have entered your activity. The User Name entry is pulled
from the User Name field in the Settings table. If "User"
appears, go to Edit Settings on the ADMINISTRATION
form, and enter your name under Control Text following "UName"
in the Control table. Close the ACTIVITY LOG form
by clicking on Done. Close the ADMINISTRATION
form by clicking on Close.
Printing the Analytic Report was discussed in a
previous section of the tutorial.
Import
The import process is discussed in detail in the System
Reference section of the documentation. This tutorial highlights some of
the important import options, and walks you through both successful and
unsuccessful imports, to demonstrate the common problems encountered
during the import process.
Import Wizard Options
The program displays a series of screens to walk you
through the import process. We call these screens the Import Wizard.
Page 1 Key Options
Click on the Import button on the MAIN
MENU. On the first screen, you can start a new import, edit the Import
File table from a previous import, resume a previous import, or undo a
previous import. The form is shown in Figure 10.
|
|

Figure 10 - IMPORT
WIZARD form for file selection.
|
|
To view the other screens in the import wizard:
- Select "DTS 1.4 Excel" for the file format.
- Select the "SuccessfulImport.xls" file from the program
directory (default C:\Enviro\Edata).
- Click Next.
Page 2 Key Options
The second page of the import wizard contains options
for checking data prior to import. Default selections are provided with
the program files, however, you can make different selections depending on
your data needs. The second page is shown in Figure 11.
|
|

|
|
Figure 11 - IMPORT
WIZARD form for checking options. |
|
The program identifies unique samples based on station,
sample date, sample matrix, filtered sample, and sample top and sample
bottom. This system allows the Data Administrator to import multiple
samples related to one sampling event, or make multiple imports of
analyses from a given sampling event. Re-analyses or analyses delivered at
different times are matched to the correct sample event by the import code
using the unique fields listed above. |
|
The Duplicates and Supersededs section of this
form tells the program how to help with importing duplicate samples as
well as multiple sets of analyses for a given sample, including the
original analyses, dilutions, reanalyses, QC data, etc. Select Auto
Update to have the program set the duplicate and superseded flags so
that more than one like sample and analysis data set can be imported.
The Sample Data section allows you to update
depths at import time instead of having to edit the import file. You can
also tell the program to allow data with null sample depths to import,
which bypasses one of the mandatory import checks.
The Analysis Data section deals with the
requirements of a relational database system. Many fields in the database
are linked to lookup tables that help to maintain consistency in data
reporting. These fields must not be blank in the data going into the
database. The qualifier codes section of this page sets required codes
such as analytic flag (often left blank by labs for valid data), analytic
problems (often not included in lab EDDs), and validator flags, to
database consistent flags, such as "v" for detected value, and
"z" for unknown. If the Check Validity option is
selected, the program compares flags reported in the import file to flags
listed in the database.
Content filtering allows you to flag or delete data
that you know is suspect, and that you want to view or delete before
import, or to flag data that may require further research before import.
The Units option allows you to convert to
consistent units the reporting units for data being imported at the time
of import. This option requires that a conversion between the reported
units and the converted units be entered into the UnitsConversion
table.
1. Select the defaults for these options, and click on Next
to view the next page of the wizard.
Page 3 Key Options
The third page of the import wizard displays Options
after Checking. The program imports the selected data file into a
temporary table, and performs the checks as requested on the previous
page. These checks may be successful or unsuccessful. The third options
page of the wizard is shown in Figure 12.
|
|

Figure 12 - DATABASE
IMPORT WIZARD form for options after checking. |
|
Options available after an unsuccessful check include:
Tell the program to help you match data, including
parameter names, station names, and reporting units,
Display the import table to allow you to edit problem
records,
Export an intermediate file in Data Transfer Standard
(DTS) format to send to a laboratory or other parties for checking, or
Export deleted records to a text file.
Options available after a successful check include:
Print a report, to check that the data was imported
correctly,
Import (you can run the data checks without importing
the data if you wish),
Notify if samples or analyses are already present, in
case the data has been previously imported,
Supersede values if present. If the data you are
importing are re-analyses, this option should be selected.
Next we will perform some sample imports.
- Click on Cancel to return to the MAIN MENU.
Import Stations
In Enviro Data,
stations are imported in a separate step from the samples and analyses.
First we will inspect a file containing some stations for import, and then
we will import those stations into the sample database.
- From Excel, open the file ImportStationExample.xls located in the
program folder (default is C:\Enviro\Edata).
Note the fields that are populated. Due to the
relational structure of the program, all required fields must be populated
before stations can be imported.
- To begin a new import, return to the
Enviro
Data MAIN MENU.
Click on Import.
Click on the right arrow below File Type And Format to select
a formatted data import from the drop down list.
Select Stations Excel.
Then browse to the program folder and select "ImportStationExample.xls".
The station import does not use any of the options on the following
screens, so select Finish.
The import notifies you that three stations out of
three in the file have been imported.
Import Samples and Analyses
Next we’ll walk you through a successful and an
unsuccessful import, to show the various features of the import process.
- Prior to import, check your data file for obvious errors.
- Open up the SuccessfulImport.xls file in Excel.
- Note that there is a header row in this format. A header row is
required for the Excel format import.
- Note the fields that are populated. As with the station import, the
relational structure of the database requires that some fields be
populated at import time.
- Close Excel, and select No if prompted to save
changes.
Successful Import
Now we’ll import samples and analyses into the sample
database. The first file we’ll import shows the results of a successful
import.
- Click on the Import button.
- Select "DTS 1.4 Excel format" and the "SuccessfulImport.xls"
file.
- Accept the default options and click Finish. The
progress meter at the bottom of the form shows the checks that the
program is performing.
- At the end of the import, the import results screen tells you that
15 records were imported out of 15 in the import file. The highest
duplicate and superseded numbers are also displayed as data checks.
- Click on OK.
The Data Review report lists the data that was
imported, and posts the import results screen at the end. Print the report
if you’d like by selecting File/ Print. Close the report
by clicking on the at the
upper right corner of the report form.
The ACTIVITY LOG form appears, and the
program inserts the number of records imported, the sample dates, and the
import file name into the activity description field.
Click Done on the ACTIVITY LOG
form. The program returns you to the MAIN MENU.
Problem Import
Import attempts are not always successful, but Enviro
Data helps you work through many typical import
problems.
Unsuccessful Import
Now we’ll try an unsuccessful import file.
- Click on Import.
- Select "DTS 1.4 Excel format" and the "UnsuccessfulImport.xls"
file.
- Click Next to go to the second page of the Import
Wizard.
- Click Configure in the Content Filter section
of the page.
- Select "Refining Inc." for the Site, then select
"LongName" under Data Field (this is field that
contains the parameter name in
Enviro
Data). Type in "Anthracene" under Data
Value, and click in the checkbox under Delete. Select
"Contains" under the Compare field. This will cause the
program to delete the Anthracene records before import. You have the
option to export the deleted records to a text file if you like.
|
- Click Back to return to the Import Wizard option
screens. Enter your activity in the ACTIVITY LOG and
click Done.
- Click Next to move to Options After Checking.
Under After Unsuccessful Check, click in the checkbox next to
the Edit Import File Table. Then click on Finish.
The first screen that appears is Match Station
Names. The Old Name is "MW14".
Click on the dropdown list under Change To: to
view station names from the database Stations table.
Select MW-14 from the list.
The program asks you to confirm the change. Select Yes.
If the correct station is not on the list, use the Add
Station button to open the STATIONS edit screen
and enter a new station in the Stations table.
The next screen that appears is labeled Confirm
Change Based on CAS Number. The program did not find a match with
the parameter name "Benzene – total" in the Parameters
table. It has found a match, Benzene, with the reported CAS number.
This screen prompts you to change the parameter name
to the name in the database corresponding to the reported CAS number.
Click Yes to accept the change.
The next screen that appears is Match Parameter
Names. pH is shown under Old Parameter Name. The
corresponding parameter name in the Parameters table is
"Field pH", however, since there is no associated CAS number
with pH, the program is unable to propose a match.
- Click on the combo box under Change To: to view the
list of parameters in the Parameters table.
- Type in "Field", then open and select Field pH from the
list.
- The program asks you to confirm the change. Select Yes.
The next screen that appears is Match Reporting
Unit Names. The Old Name is shown as "ug". There is
no corresponding unit in the Reporting Units lookup table in Enviro
Data.
- Use the dropdown box under Change To: to select the correct
unit, ug/l, and confirm the change.
Edit Import File
The Edit Import File screen appears next. This
table displays all of the information for all of the records in the import
file. Note that the first several records say "No problems"
under Import Problem.
- Click on the Problems Only button. Now the first
record lists a Sample Matrix problem. See that there is a
"W" entered in the sample matrix field, while the record
with "No Problems" has "Water" entered as the
matrix. "W" is the code for water in the Sample Matrix
lookup table, however, the program is expecting the description,
"Water", in the import file, not the code.
- Type "Water" into the Sample Matrix field for this record.
NOTE: Editing the flag here does not change the data in the original
import file, only in the temporary import file created at the start of
the import.
- Click on Finish.
- An Import Errors report is generated by the program, which shows the
records that did not meet the consistency checks for entry into the
database. This report can be printed to track data that was corrected
during import.
- Close the report by clicking on the
at the right corner of the report, and you are returned to the MAIN
MENU.
Resume Last Import
Click Import again.
Then click Resume Last Import. The import begins from
the Edit Import File temporary table, and checks that the
changes you made are consistent with database entries. The Import
Results screen appears on successful completion of the import, and
notes that three records were deleted from the import file.
Click on OK. The ACTIVITY LOG and
associated activity appears.
Click on Done. Notice that the Data Review report does
not contain any Anthracene records.
Content Specific Filtering
If you had selected "Mark" instead of
"Delete" under Content Specific Filtering, the Anthracene
analyses would have been displayed in the Edit Import table for you
to view. You have the option of selecting records for deletion from the Edit
Import table. Or, if the records are satisfactory, rerun the import
and uncheck the Content Specific Filtering option. The records are
then imported.
Edit ImportFile Table
If you encounter problems in an import file that
require additional research, you can view and print the Import Errors
report, discontinue the import, and even close down the program. When you
return to this import, you can move directly to the Import File table by
selecting Import, then Edit ImportFile Table.
If you import another file in the meantime, however, you must start the
import of the problem file at the beginning, unless you save the partially
edited data to a DTS file. In that case, you can re-import the saved file
and proceed from there.
Undo Previous Import
To undo the import just completed,
- Click on Import, then Undo Previous Import.
The Undo Import screen lists important information about the imports
that you’ve made.
- Select the most recent import, with sample dates of September 1999.
Click Undo Selected Import, and confirm the choice.
- The ACTIVITY LOG appears with information about the
deleted file entered by the program. Click on Done. The
September 1999 data has been deleted from the database.

Admin
Enviro Data provides a variety of
tools to help you work with your data. Depending on the task to be
accomplished, some of these activities require manual entries, while
others provide varying degrees of automation.
Edit
Changes to data are usually made through editing forms.
These forms reflect the structure of the database, with forms for Sites,
Stations, Samples and Analyses (primary data), as well as for lookup and
other data. For the forms for editing the primary data, there are two ways
to display them, unselected and selected. We will go through both ways in
these exercises.
Sites
The highest level of primary data is Sites. We will
view this data without making a selection.
- From the MAIN MENU, select Admin. Then
click on Sites.
- The SITES form initially displays in form view. It has
three tabs for different data elements related to Sites. Form view
lets you easily see all of the data for one site.
- Switch to datasheet view by clicking on the Datasheet
button in the upper left corner. Datasheet view lets you see data for
many sites at once, and lets you choose one for editing. Double click
on the gray box to the left of "Refining Inc." to choose
that record and return to datasheet view.
- You can move between records using the record selectors at the
bottom of the form. Move up one record to "Rad Industries"
by clicking on the
button.
- The form has three tabs. The Site Data tab, which is
displayed when you enter the form, has general information about the
site.
- Click on the Link Labs & Contractors tab to view that
data. This tab lets you assign laboratories and contractors to each
site, so you can create a reference file for them to test imports
against.
- Click on the Regulatory Limits tab to view that data. This
tab is used to assign regulatory limits and numbers of expected
observations for each parameter for each site and sample matrix. It
has two tabs, Site-Specific and All Sites. Limits can be
assigned that apply to all sites in the database, or just to one site.
Click on the Site Data tab to return to the site general data.
Deleting Records
You can delete records from the editing forms, either
in form view or in datasheet view.
- In form view, click on the gray bar to the left of the site data.
This selects the record. Press the Delete key on the keyboard, or
click on Edit/Delete Record. Access will display an
error, because of "Referential Integrity". In this case, it
is complaining that records in the SiteLabLink table refer to
this site. It could also happen if child records are present in the Stations
table. To overcome this, you would need to delete the child records
(and their children, if present, etc.) before you could complete the
deletion of the record. This process helps you protect your data from
"orphan records", where the child is there, but the parent
is gone. Click on OK to confirm that a record won’t be
changed.
- Close the SITES form, edit the ACTIVITY LOG
form, and close it. Close the ADMINISTRATION form to
return to the MAIN MENU.
If you wish, you can use a similar process for editing
the Stations and Samples tables.
Analyses
To edit a record in the Analyses table, we will
go through the selection process. This is a good idea, especially in large
databases, because you don’t usually need to access all of the analyses
records to edit the ones that need changing.
- On the MAIN MENU form, click on Analytic Data.
This will bring up the SELECT DATA form.
- Click on the Save/Load tab, and select "Sulfate
Graph".
- Click on the Modify tab and click on Edit. Then
click on Analyses. This will display the ANALYSES
form. At this point you can edit any data in the form.
Choosing a Sample
One aspect of this form deserves special mention. That
is choosing a sample for the analysis. The form helps you select a sample
by displaying a combo box from which you can select a sample.
- Click on the
button
under Sample near the top of the form. This will display
a scrollable list of samples from which you can select the correct one
for this analysis. Don’t make any changes. Press the Escape key to
close the list.
- Close the ANALYSES form, and fill out and close the ACTIVITY
LOG form. Close the SELECT DATA form.
|
|
Lookups
Enviro Data
contains a set of tables to assist with data consistency through
referential integrity. These tables are called "lookup tables"
and contain coded values. The software comes with some data in these
tables, and the Data Administrator can make changes as necessary to suit
project needs.
- From the MAIN MENU form, click on Admin,
then Station Types. Click on Datasheet.
You will see a list of the station types currently in the database.
Close the STATION TYPES form. Fill out the ACTIVITY
LOG form and close it.
- Click on Parameters. This is a more involved form,
since there is quite a bit of additional information that is carried
along with the parameter name and number. Look at the fields. Then
close the PARAMETERS form. Fill out the ACTIVITY
LOG form and close it. Close the ADMINISTRATION
form.
One warning about the lookups is that care should be
taken in editing the data, since data in the primary tables may depend on
these values. Referential integrity will prevent you from deleting a
lookup value that is needed by data in a primary table. The software has
no way to prevent you from making a valid, but incorrect, change. If you
change "mw" in the StationTypes table to mean "Soil
Boring" instead of "Monitoring Well", then stations with
that code will now be incorrectly labeled.
Other Modifications
There are a number of other data management functions
that the software helps you perform. This section will cover just a couple
of these functions.
|
|
Data Review
In addition to helping you manage your data, Enviro
Data also helps you keep track of what level of data
review each data item has had. You can do this by selecting a set of data,
and then changing the review status for that set of data.
- In the SELECT DATA form, click
on Reset. Display the Analyses panel.
Enter a S. Date of "00" and click on Update.
Click on the Modify tab, and select Review. This
form shows the current review status of the data, and allows you to
change the review status for the selected records. We won’t change
anything here.
- Click on Close, then fill out and close ACTIVITY
LOG.
Duplicated Records
The software also helps you
identify and clean out any duplicated records at the samples and analyses
levels.
- Using your previous selection, click on Duplicates.
Any duplicated records at the samples level will be displayed. You can
move analyses between samples, and then delete unnecessary samples
using this screen. Click on Continue.
- Any duplicated records at the analyses level will be displayed. The
software will suggest which records should be deleted. You can change
these selections if you wish. Click on Cancel.
Hopefully these few exercises will give you a feel for
what can be done with Enviro
Data. The next section will cover some concepts that
you might find helpful in working with the program. The section after that
covers all of the features of the software in detail.
