The format of these values is shown in the following table. | Name | Data type | Data | | :--- | :-------- | :--- | | *data-source-name* | REG_SZ | *driver-description* | |   |   |   | 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: ```console Inventory : REG_SZ : SQL Server Payroll : REG_SZ : dBASE Personnel : REG_SZ : Text ```
