Many Windows applications will read and write information to a database. To separate the application from the database engine that’s running, a technology called ODBC (Open Database Connectivity) comes into play. ODBC allows an application developer to create an application without any concern for the type of database that will be runnning on the backend. The application developer can then focus on the application function, and the end user can decide what type of database they want to use in their environment.
Administrators are able to configure the connection between the application and the database in the ODBC Data Sources from the Control Panel under Administrative Tools.
