A computer system is provided with a database containing stored data, an application adapted to provide a user interface to a user operating the computer system, the application having a first view of the data stored in the database, a data manager having a second view, different from the first view, of the data stored in the database, and a session manager interfaced between the application and the data manager. The session manager is adapted to receive from the application a first request for data formatted according to the first view of the data, translate the first request for data into a second request for data formatted according to the first view of the data , and forward the second request for data to the data manager. In this way, the application is able to access data stored in the database without requiring the application to have knowledge of the second view of the data. The session manager may also be further adapted to receive from the data manager a first response containing a first subset of data formatted according to the second view of the data, translate the first response containing the first subset of data into a second response containing the first subset of data formatted according to the first view of the data, and forward the second response containing the first subset of data to the application.
