iODBC stands for Independent Open Database Connectivity. Commonly considered to be specific to Linux or UNIX platforms, iODBC is a truly platform-independent Open Source implementation of ODBC.

The iODBC SDKs for the Mac provide support for Cocoa, Carbon, and Darwin development. Like ODBC on the Windows platform, iODBC comprises the following:
