Setting up a connection to the e-Ecology database

Connecting to the FlySafe database via Access or other relational database programs

General Information

The Flysafe database is a spatial postgreSQL ([1]).

PGAdmin can be used to browse and query data. If you use pgadmin you do not need to set up an ODBC connection.

Database can also be called from other programs by installing an ODBC driver for postgreSQL and establishing a "User Data Source" [2]

In order to access the database your IP address must be sent to Bart Heupers who will provide a user name and password. For organizations an IP range can also be given.

Flysafe server information

server : flysafe-pps.grid.sara.nl

        port 5432
        ssl required

The tracking data can be found in schema "gps". However these instructions can be followed for any of the data included in the flysafe database.

Setting up an ODBC connection

ODBC (Open Database connectivity) is a standard method of sharing data between databases and other programs. ODBC drivers use SQL to gain access to data from sources outside the program. Therefore, in order to connect between your database and other programs you must set up an ODBC connection. Step 1: Download and install an ODBC driver for postgreSQL. [3] Step 2: Set up ODBC connection

Do the following:

1. go to ‘‘‘start | Control panel | Administrative tools | Data sources (ODBC)’’’
2. go to ‘‘‘User DSN’’’ (first tab in Data sources)
3. click ‘‘‘ADD’’’
4. in window ‘‘‘create’’’ ‘‘‘new data source’’’ select ‘‘‘PostgreSQL ANSI’’’ click ‘‘‘FINSH’’’
5. The ‘‘‘ODBC Driver setup’’’ window opens. ‘‘‘Data source name’’’: give your data source a name (eg GPS). Keep it simple, easily identifiable, this is the name you will use to identify your database from other applications, this will be the ‘‘‘ODBC driver name’’’.
6. In the same window fill in the following information: ‘‘‘database’’’ ‘‘flysafe, ‘‘‘‘‘Server’’’ ‘‘flysafe-pps.grid.sara.nl, ‘‘‘‘‘User Name’’’’’ your user name, ‘‘‘‘‘SSL Mode’’’’’ require, ‘‘‘‘‘Port’’’’’ 5432, ‘‘‘‘‘Password’’’’’ your password. ‘‘When the window is completed click ‘‘‘SAVE’’’
7. Back in the ‘‘‘User DSN’’’ window you should now see your ODBC driver you just named, click ‘‘‘OK’’’

After completing these steps many other programs will now recognize your database and be able to communicate with it

Connecting to Access

You can now connect to the database via access. You have two options. One is to import the data, once this is done your database is not automatically updated but does not require a link to the database.

The second option (described below) is to create a dynamic link to the database (you must be connected to the network) in this case you are always viewing data that is in the actual SARA database.

1. Open a new database in Access
2. go to ‘‘‘file | Get external data | Link tables’’’
3. in ‘‘‘files of type’’’ select ‘‘‘ODBC databases’’’
4. in ‘‘‘select data source’’’ click on tab ‘‘‘Machine Data Source’’’
5. select the data source name you created when setting up the ODBC connection (eg GPS) click ‘‘‘OK’’’
6. Select the tables you want to import click OK

You now have access to your selected tables in the database. Have fun.
