Software Modernization (with TGGs)

Software Engineering is about 40 years of age. It is still hard work creating new software spreading through almost all kind of industry. Because of a growing amount of code there is always a kind of legacy system. As a consequence compatibility issues arise when new software is created or maintained. Avoid creating new software from scratch leads to a need for rethink existing software. Not only as a part of maintenance, but also because of a changing environment.

The aim of Software modernization is a systematic way of managing software evolution. This is done by extracting essential and business related parts of the system away from technical parts. The extraction leads to a collection of platform independent models. The aim of this extraction process is to retrieve a collection of the most important parts of the software that cope with the main / essential functionality and knowledge.  The next step is to re-formulate new requirements and business needs the new software has to apply to. Finally the extracted software parts, including new parts or changes, are rebuilt into a new system, with e.g. a changed technical infrastructure.


Our approach
The extraction of relevant parts of a system can be done by a technical neutral model. E.g. the description of business processes covered by a system may be described by a business process language.
Using MOFLON and included Transformation Engines based on SDM and TGG we try to automate the extraction-process first. Regarding the Architecture Driven Modernization proposals and related projects from the Object Management Group, we try to implement related technologies as the Knowledge Data Metamodel for example.
