Abstract

A reverse engineering database replication data system is disclosed. In one embodiment, the replication data system receives an input of replication configuration data for a plurality of databases and builds memory models based on metadata accessed from the plurality of databases, which are then transformed to a first platform-specific replication model. Then, based on the first platform-specific replication model, a first universal replication model is configured, which is used to create a replication visual model using the rendering canvas. A user may modify the first universal replication model using the replication visual model to create a second universal replication model, which is then transformed to a second platform-specific replication model. Finally, scripts are generated for the second platform-specific replication model, which are then provided to a memory device.
