The values under the ODBC Data Sources subkey list the data sources. The format of these values is:
| Name | Data type | Data |
| data-source- name |
REG_SZ | driver-description |
where data-source-name 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:
Inventory : REG_SZ : SQL Server
Payroll : REG_SZ : dBASE
Personnel : REG_SZ : Text
