The purpose of this module is to examine the new Oracle features related to distributed databases.
As you know, Oracle software is evolving constantly to improve database connectivity between distributed systems.
With the introduction of Oracle, we see several new features that improve connectivity between remote databases and offer improved security and replication reliability.
After completing this module, you will be able to:
The objective of this module is to provide you with enough detailed information about the new Oracle distributed features to enable you to use them in
your organization and to understand their functions well enough to pass the OCT exam.
This module assumes that you already have a baseline understanding of Oracle distributed database concepts, including snapshots and replication techniques.
Let's began by taking a closer look at each of the enhancements for distributed databases.
A distributed database system
allows applications to access data from local and remote databases. In a homogenous distributed database system, each database is an
Oracle Database. In a heterogeneous distributed database system, at least one of the databases is not an Oracle Database. Distributed databases use a client/server
architecture to process information requests. This section contains the following topics:
- Homogenous Distributed Database Systems
- Heterogeneous Distributed Database Systems
- Client/Server Database Architecture
