QMF for Windows and DB2 are distributed relational database applications that operate together in a client/server relationship. Each component plays a separate and distinct role in this relationship:
QMF for Windows and DB2 satisfy and adhere to a common architecture, IBM's Distributed Relational Database Architecture (DRDA). QMF for Windows uses DRDA to communicate to DB2. It does this by sending SQL requests (queries) to DB2. This means that QMF makes requests for the work then DB2 performs the requested work.
This architecture is a comprehensive and detailed blueprint that specifies the layers and functions required in a client/server distributed database application.
Because QMF for Windows implements the DRDA requester specification, it is capable of connecting to any database that adheres to and implements the DRDA server architecture. The following IBM database products contain a DRDA server component, and are capable of communicating with QMF for Windows:
Your DB2 QMF for Windows license determines the DB2 product on which you can install QMF for Windows and use for connections.
