Methodological Framework and Application Integration Services in Enterprise Information Systems

For integration of two business functions or two business systems it is necessary to connect their business processes with application support and data exchange. Processes appertaining to one application system create data which will be used by another application system. First, and the key reason for the integration of business systems’ applications, are user business needs for business processes and information flow, and changes in business processes occurring during business transactions. The next integration reason is related to the technological differences by means of which applications are constructed. Integration should be carried out to connect technologically different applications. Because of process complexity which includes breakdown of the existing business processes and applications, business processes change on the basis of business needs and user requirements, modeling of such processes, and new applications and their connection, it is necessary to shape methodological framework. The use of this framework should result in the successful completion of EAI projects.
