1.1 Why Reverse Engineering

This topic Describes the reverse engineering importance.

As the complete ER diagram of OBTR application would be huge, the business application developers need to re-engineer with required filtered portion of OBTR to get specific portion of data model. Example: There is a business requirement to add additional fields to customer personal information.

The business developer could filter the Customer specific entities from OBTR Database schema and generate the ER diagram. This ER diagram further can be used to understand the OBTR and can be foundation for further business development requirement.
