Open Database Connectivity (ODBC) A standard database access method developed by Microsoft™. ODBC should make it possible to access any data from any application regardless which DBMS is handling the data. ODBC manages this by inserting a middle layer between the application and the DBMS. This layer will translate the applications queries into commands the DBMS will understand, however both the application and DBMS must be ODBC compliant.
