ODBC (Open Data Base Connectivity )

It's a standard that allows access to databases regardless of their internal format and engine. Please note database file and data source are distinct notions. db2dir handles datasources not files.

Basically, a datasource is the combination of
a name eg: "gep99-DB2DIR"
a driver eg: "Microsoft Access Driver" )
a file eg: "c:\admin\gep97.mdb" )

You  don't have to have Microsoft Access installed to use db2dir.

How to check if ODBC is installed

The configuration panel displays the available ODBC datasources. The datasources that db2dir has generated are  -DB2DIR suffxed.

Open Control Panel then ODBC. Check for the presence of ODBC drivers, particularly the Access driver that is used to create a database. The Text driver is used to import data from text files.
