Earlier chapters of this book provide information about accessing distributed data in the client/server environment. “Distributed data” on page 60 introduces basic client/server concepts, and “Web application environment” on page 361 has information about connectivity between DB2 UDB for z/OS and other servers.

This chapter explains what happens to your data in a distributed computing environment, programming techniques that are unique to this environment, and performance considerations.

The distributed environment supports both a two-tier and a multitier architecture. “Web application environment” on page 361 has information about the various client/server configurations that these architectures offer.
