What is reverse engineering and how well does it work?
What will be an ideal response?
Reverse engineering (RE) is the process of reading the database schema of an existing database and using it to reconstruct a data model of the database. It works fairly well, but does have significant limitations. First, RE produces conceptual schema errors because it creates an entity for every table in the database including intersection tables in N:M relationships which would not be an entity in the original data model. Second, it does not generate internal schema information such as referential integrity constraints. Therefore, the result, which the authors call the RE data model, is a good starting point for analyzing an existing database but is not a complete solution.
