# Overview The title is a bit verbose, so it doesn't get confused with the concept of [[Database Replication]]. In this case, we are replicating the data outside a source system, so it can be used for further processing without interfering with any business critical applications. It is essentially just the E and L from [[Extract, Load, Transform (ELT)]], where we don't do the T so we can preserve a version of the "raw" data and handle transformation further down in the architecture. # Key Considerations # Implementation Details # Useful Links # Related Topics ## Reference #### Working Notes #### Sources
