Open Database Connectivity (ODBC)

ODBC is a standard or open application programming interface (API) for accessing to database management systems (DBMS). This API is independent of any one programming language, database system or operating system. ODBC is based on the Call Level Interface (CLI) specifications from SQL, X/Open (now part of The Open Group), and the ISO/IEC. ODBC was created by the SQL Access Group and first released in September, 1992.

By using ODBC statements in a C++ program, you can access files in a number of different databases, such as, MS Access, MS SQL, Oracle, DB2 and My SQL. In addition to the ODBC software, a separate module or driver is needed for each database to be accessed.
