22.1 Introduction
The concept of a distributed system was introduced in Chapter 2. A distributive database
system consists of a collection of sites, connected via a communication network in which:
•
Each site is a database system in its own right.
•
The sites work together (if necessary) so that a user at any given
site can access data at any other site as if the data resides of the
host (user's) site.
