Difference between DB2 servers and IBM data server clients

Here's the answer :-) :

A DB2® database system consists of a DB2 server and IBM® data server clients.

A DB2 server is a relational database management system (RDBMS) that delivers data to its IBM data server clients. You need to install a DB2 server if you plan to use a database that resides on this computer.

An IBM data server client is an application that allows you to run commands and SQL statements against a DB2 server, connect to a remote DB2 server and access its databases. The following types of IBM data server clients are available:

• IBM Data Server Client
• IBM Data Server Runtime Client
• IBM Data Server Driver Package
• IBM Data Server Driver for ODBC and CLI
