Program Abstraction and Re-Engineering: An Agile MDE Approach

In this paper we describe an Agile model-driven engineering (MDE) approach for the re-engineering of legacy systems. This involves the automated abstraction of systems to UML specifications and the interactive application of refactoring and rearchitecting transformations to improve system quality. The approach is demonstrated on Visual Basic and COBOL legacy codes, including a finance industry case. Significant quality improvements are achieved, and translation accuracy over 80 % is demonstrated.
