The values under the ODBC Data Sources subkey list the data sources. The format of these values is as shown in the following table.
The data-source-name value is defined by the administration program (which usually prompts the user for it), and driver-description is defined by the driver developer (it is usually the name of the DBMS associated with the driver).
For example, suppose three data sources have been defined: Inventory, which uses SQL Server; Payroll, which uses dBASE; and Personnel, which uses formatted text files. The values under the ODBC Data Sources subkey might be as follows:
Inventory : REG_SZ : SQL Server Payroll : REG_SZ : dBASE Personnel : REG_SZ : Text
