Information Systems Integration through Message Transfer System: Planning Phase

Huge and complex business systems are usually supported by previously developed or inherited information systems, which have been developed on the basis of business functions standard model. Such information systems cover a particular business fields, but, since they have been developed in an independent and uncoordinated way, there're modest possibilities of interacted automated data exchange because of heterogeneous data, first of all. Because of increasing data exchange needs, resulting from interconnectedness of business processes and permanent changes in internal and external circumstances, development and upgrading of programme procedures is an imperative. In this connection it is necessary to find ways and means to integrate all existing information systems in given circumstances and render possible exchange and usage of all needed data in a reliable and consistent way. The problem can be solved organizationally and technically in different ways and this paper, within information system planning phase, investigates the possibility to use message transfer system. This implies initiation of automated data exchange between existing information business systems providing for full scale control and management of mutually exchangeable data. Chapter 1 and 2 deal with the necessity to integrate information systems of a business system ; the concept of solution model is given as well. Chapter 3 explains technical aspects of examined integration solution at logical level. Possibilities to enlarge the elaborated approach on future integration processes in relation to a business system external circumstances are examined in Chapter 4. Conclusive Chapter 5 reveals benefits which can be achieved by application of proposed concept of the information systems integration. The approach itself is open for enlargement, dynamic adjustements and extensions needed to fulfill business system needs.
