Oracle7 Server Concepts

CHAPTER 21. Distributed Databases

Good sense is of all things in the world the most equally distributed, for everybody thinks he is so well supplied with it, that even the most difficult to please in all other matters never desire more of it than they already possess.

Rene Descartes: Le Discours de la Methode

This chapter describes what a distributed database is, the benefits of distributed database systems, and the Oracle distributed database architecture. The chapter includes:

An Introduction to Distributed Databases

Replicating Data

Note: The information in this chapter applies only for those systems using Oracle with the distributed or advanced replication options. See Oracle7 Server Distributed Systems, Volume I and Oracle7 Server Distributed Systems, Volume II for more information about distributed database systems and replicated environments.

If you are using Trusted Oracle, see the Trusted Oracle7 Server Administrator's Guide for information about distributed databases in that environment.
