I want to know, how the Oracle Warehouse builder or Data Integrator fetch the data from Oracle database, say for example oracle Golden gate is used for online replication which reads the data from REDO log instead of fetching the data from TABLE (Storage Disk), because it's oracle product.

The above mentioned ETL's is from Oracle, so I want to know is any performance improved architecture is adapted? when compare to other ETL tools like informatica.

Thanks & Regards
