Data warehouses are user-driven; therefore, a very important aspect of data warehousing research would be studying the interaction between end-users and data warehouses. As user satisfaction is commonly acknowledged as the most useful measurement of system success, we intend to identify in this article the underlying factors of end-user satisfaction with data warehouses, especially the roles of information centers in the use of data warehouses. The study demonstrates that most of the items in classic end-user satisfaction measure are still valid in the data warehouse environment and that end-user satisfaction with data warehouses heavily depends on the roles and performance of Information Centers in organizations.
