What are functions of client and server?

In a client-server database system, the application program is stored on the client computer and DBMS is placed on the server computer. Another piece of software that is placed on the client is known as DBMS driver. The DBMS driver receives the processing requests from the application program and sends to DBMS. It also receives responses from the DBMS and sends them to an application program.
