Abstract

The software systems evolve and new modules and dependencies are added to support new features, while obsolete functionality is removed. Consequently, the design gradually diverges from its original design. Different design artifacts become inconsistent with the current implementations, making software evolution and servicing tasks difficult and error prone. This study describes a Reverse Engineering Abstraction Methodology (REAM) used to recover the design artifacts from the source code and available documentation. The methodology consists of (five models) high level, functional, architectural, source code and mapping models and these models represent the information of the subject system artifacts at different levels of abstractions for maintenance task at hand.
