Abstract:
Most established companies have acquired legacy systems through mergers and acquisitions. The systems were developed independently of each other and very often they do not align with the evolving IT infrastructure. Still, they drive day-to-day business processes. Replacing the legacy application with new solutions might not be feasible, practical or cost a considerable amount of time. However, immediate integration might be a requirement for a strategic project, such as supply chain management or e-business. This article presents a transformation system for legacy system integration that allows flexible and effective transformation of data between heterogeneous systems. Sequences of transformations are described using a grammar based approach.
