Oracle golden gate is a data replicant solution that is seperate from the oracle database.
It is a distinct product that needs to be install and configured separately and request its own licence.
This solution allows from the replication of the subset of data in one database to another subset of data in different database.
One of its most powerful future is to ability to replicate between none.
Oracle database such as replicating some tables in an Oracle database to some tables in SQL server and vice versa.
Another strong feature of this product is its PI directional replication capability.
You just can connect and make changes to data bases on either side whether it is the source or destination Database and golden gate takes care of implementing the changes on each database.
You might wonder about the difference between data card and Golden Gate while data guard also replicates data from the primary database to the standby database, Golden Gate offers more control over what data gets replicated, allowing for replication of just a subset of data.
Additionally the bi directional replication feature sets Golden Gate apart from dataguard.
