Matching and Adaptation: Core Techniques for MDA-(ADM)-driven Integration of new Business Applications with Wrapped Legacy Systems
نویسنده
چکیده
In this article, we introduce a methodology aiming to blend modern business applications, which consist of cooperating business components with objectified legacy systems. This methodology is designed in line with the MDA(ADM) philosophy. This legacy application integration methodology encompasses three phases: forward engineering, reverse engineering and linking. The forward engineering phase resembles the “classical” MDA process, starting from a (enterprise) CIM and transforming it into a PIM. The reverse engineering phase reverses this process, extracting concepts from legacy code and data and rendering them into a PSM, and then abstracting it into a legacy PIM. During the linking phase, both the new PIM and legacy PIM are matched and adapted, so that only those fragments of the new PIM need to be coded that are not yet supported in legacy systems.

The problems of enterprise interoperability, portability, maintenance and integration are not exactly new. From the first time code was stored in memory, the problems of legacy integration with new users and new uses of computing systems began. The explosion of computing vendors and tools hasn't exactly made the problem any easier. In fact, it's the explosion of information in general that is c...
متن کاملModel-Driven Integration of Business Information Systems
The integration of business information systems is an important task for enterprises, with an increasing demand on the level of integration. While most integration projects in the past concentrated on the integration of data used by different applications, today the focus is on the integration of the applications themselves. Furthermore there already is a tendency towards the integration of sys...

puter application software has revolutionized the way organizations share and manage their information. Rather than develop custom information systems with their internal programming staffs, many businesses now purchase software available in standard “off-theshelf ” packages. A well-chosen standard package can save development time and cost. Before it can be useful, however, it must be integrat...
