Combining a flexible data model and phase schema translation in data model reverse engineering

A data reverse engineering tool whose input can be from heterogeneous legacy systems which can range from COBOL record layouts to DB/2 data definitions needs to be able to utilize a flexible data model as well as phase schema translations. The flexible data model allows a designer to fully understand the legacy system as well as know what corrections could be made during conversion to a new implementation. The phase schema translation takes the database designer through the reverse engineering process in such a way that the user can concentrate on one aspect of the process at a time and not to get bogged down in the process itself
