Oracle Streams
From Wikipedia, the free encyclopedia
In computing, the Oracle Streams product from Oracle Corporation encourages users of Oracle databases to propagate information within and between databases. It provides tools to capture, process ('stage') and manage database events via Advanced Queuing queues.
Oracle Streams is the flow of information either within a single database or from one database to another. Oracle Streams can be setup in homogeneous (all Oracle databases) or heterogeneous (non-Oracle and Oracle databases) environments. The Streams setup uses a set of processes and database objects to share data and messages. The database changes ([DDL] and [DML]) are captured at the source; those are then staged and propagated to one or more destination databases to be applied there. Message propagation uses Advance Queuing mechanism within the Oracle databases
Applications for the Oracle Streams toolset include data distribution, data warehousing and data replication.
As of Oracle version 9.2, Oracle Corporation makes Oracle Streams available on Oracle Enterprise Edition systems only.
