Db2 servers and IBM data server clients
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. If you plan to use a database that resides on this computer, install a Db2 server. For more information about Db2 servers, see IBM DB2 - Database software - IBM Analytics.
An IBM data server client is an application where you can run commands and SQL statements against a Db2 server, connect to a remote Db2 server, and access its databases.
