Logic and object-orientation have come to be recognized as being among the most powerful paradigms for modeling information systems. The term qinformation systemsq is used here in a very general context to denote database systems, software development systems, knowledge base systems, proof support systems, distributed systems and reactive systems. One of the most vigorously researched topics common to all information systems is qformal modelingq. An elegant high-level abstraction applicable to both application domain and system domain concepts will always lead to a system design from qoutside inq; that is, the aggregation of ideas is around real-life objects about which the system is to be designed. Formal methods \yhen applied with this view in mind, especially during early stages of system development, can lead to a formal reasoning on the intended properties, thus revealing system flaws that might otherwise be discovered much later. Logic in different styles and semantics is being used to model databases and their transactions; it is also used to specify concurrent, distributed, real-time, and reactive systems. , The notion of qobjectq is central to the modeling of object oriented databases, as well as object-oriented design and programs in software engineering. Both database and software engineering communities have undoubtedly made important contributions to formalisms based on logic and objects. It is worthwhile bringing together the ideas developed by the two communities in isolation, and focusing on integrating their common strengths.Transformations supported by the framework would allow the systems to be a dynamically wireda together to support the business model. This dynamic wiring can be figured from the business process models and the application system models.
