An ODBC application makes ODBC calls to the DriverManager. The DriverManager carries out a number of tasks for the application such as:

• ensuring the proper driver is loaded/unloaded
• validation tasks
• 3.5 to 3.0 to 2.0 call and data mapping

Most calls to the DriverManager get passed onto the loaded Driver to be further processed but that is of little concern to the application.

Some advantages to using an ODBC DriverManager include:

• portable data access code
• runtime binding to a Data Source
• ability to easily change the Data Source
