Note: The Control Center and its associated components were deprecated in Version 9.7 and might be removed in a future release. We recommend that you use the new suite of GUI tools for managing DB2 data and data-centric applications. These new tools include the IBM Data Studio, the Optim Development Studio, and the Optim Database Administrator. 2.2 IBM DB2 SSacSA architecture In a typical Sybase ASE database architecture, the client drivers (DB-Library, CT-Library, ODBC, JDBC, and so on) are responsible for taking requests from the client application and communicating them to the database. The client application utilizes one of the Sybase client drivers to communicate with the database server. Figure 2-9 shows the CT-Library being used for application communication. The database server contains various resources accessed by the client application, such as tables, views, triggers, stored procedures, and functions (to name the most frequently used resources). The applications access these resources by calling the functions in the CT-Lib driver. The driver passes the functions along with the arguments to the database server either through Sybase T-SQL or by making explicit procedure calls to request the database server run a specific stored procedure.
