Towards Applying Model-Transformations and-Queries for SOA-Migration

In today’s businesses, a lot of monolithic legacy systems exist. In order to allow for a higher flexibility and a better alignment to the ever-changing business processes, migration to service-oriented architectures is often intended. In most cases, this is done by wrapping the legacy system with an additional layer providing functionality as services. But this approach does not result in more flexibility, because the old system is unchanged. This paper proposes the extensive use of model-driven techniques, like model-querying and transformations, for migrating legacy assets into service-oriented architectures. The techniques used were evaluated in a first attempt at migrating parts of the functionality of the open-source tool GanttProject into a service.
