The abstract interface to a particular database platform.

For each database platform the separate subclass implementing this interface should be defined. In particular, this toolkit provides the subclass of CSqlInterface implementing interface to ODBC 3.5 data sources. This subclass is supplied by the implementation part of SqlOdbc namespace.

Each SQL interface is assigned the certain type. Type is an implementation-dependent string, which uniquely identifies the platform supported by this interace. The string "odbc" (lower-case) is reserved for all versions of ODBC.
