The best replication tool on the market

We use GoldenGate to replicate some of the data from the production database to a data warehouse. It is used by the IT department. By using GoldenGate we don't impact the production database. We can run queries or reports or any long queries from the replicated database using GoldenGate. At one time we even used GoldenGate as a DR database and replicated entire production database. By doing so, one time when we had an outage and lost the production database, this DR became available to us and switched it to the primary. So we have a lot of advantages when using GoldenGate. We can replicate some tables or all tables and different scenarios of replicating data using functions and triggers. The business problem it addressed was less impact on production databases, more realtime data available to the business without putting an overload on production databases.
