Object-oriented Modeling Toolkit and Technological Framework for Legacy Information Systems Reengineering

Software reengineering is a very difficult and expensive process, which requires as a lot of “mechanical” activity: by restructuring of the legacy source code to a new one, and a human intervention by high-level restructuring: for the changes needed in overall legacy system behavior scenario, and in the system architecture. That is why a very important problem is the forming of an effectively Modeling Toolkit and Technological Framework (MTTF), which would be adequate for appropriate OO reengineering paradigm. One of the key component of this complex will be the Domain Ontology Maintenance Facility (DOMF). It is designed and will be implemented as the completely Internet/intranet-based application, using J2EE, JSP, and Oracle 8i Suite technologies. It also allows the external experts, who have to be involved in the process of system reengineering or maintenance, to participate on ontology specification processing in the remote mode via Internet.
