Software Modernization
3 likes1,622 views
The document provides an overview of software modernization and related concepts such as reengineering, reverse engineering, restructuring, and forward engineering. It discusses architecture-driven modernization (ADM) and some of the key standards and models in ADM, including the Architecture-Driven Modernization Specification (ADM), the Knowledge Discovery Metamodel (KDM), and the Software Metrics Metamodel (SMM). The document also provides examples of using ADM approaches like MoDisco for tasks such as migrating from JUnit 3 to JUnit 4.

- 12. Calling things properly Reengineering "The examination and alteration of a software system to reconstitute it in a new form and the subsequent implementation of a new form. Generally includes some form of reverse engineering, followed by some form of forward engineering or restructuring." E. Chikofsky and J. Cross, “Reverse engineering and design recovery: A taxonomy,” Software, IEEE, vol. 7, no. 1, pp. 13–17, 1990.
- 13. Calling things properly Reverse Engineering "Process of analyzing a subject system to identify its components and their relationships and to create representations of the systems in another form or at a higher level of abstraction. Generally involves extracting design artifacts and building or synthesizing abstractions that are less implementation- dependent..." E. Chikofsky and J. Cross, “Reverse engineering and design recovery: A taxonomy,” Software, IEEE, vol. 7, no. 1, pp. 13–17, 1990.
- 14. Calling things properly Restructuring "Transformation for one representation form to another, at the same abstraction level, while preserving the subject system external behavior (functionality and semantics)" E. Chikofsky and J. Cross, “Reverse engineering and design recovery: A taxonomy,” Software, IEEE, vol. 7, no. 1, pp. 13–17, 1990.
- 15. Calling things properly Forward Engineering "The traditional process of moving from high level abstractions & logical or implementation independent designs (e.g. models) to the physical implementation of a system (e.g. source code)." E. Chikofsky and J. Cross, “Reverse engineering and design recovery: A taxonomy,” Software, IEEE, vol. 7, no. 1, pp. 13–17, 1990.
