MDAC 2.5 SDK - ODBC Programmer's Reference
Chapter 19: Configuring Data Sources
Information about data sources is stored in the system registry. Users modify data source information through an administration program. This can be the ODBC Administrator shipped with the Microsoft® Data Access Components (MDAC) SDK, the ODBC Control Panel device, or an administration program written by an application or driver developer.
Note This chapter is specific to Microsoft Windows® platforms. How data sources are configured on other platforms is platform-specific.
