informatics, external advisers and manufacturers. They need clear rules and limits within which they can process their individual sub-tasks, in order to ensure the logical consistency of the entire project. Therefore, an architecture needs to be established to determine the components that make up the information system and the methods to be used to describe it. The ARIS architecture developed in this book is described in concrete terms as an information model within the entity-relationship approach. This information model provides the basis for the systematic and rational application of methods in the development of information systems. Furthermore, it serves as the basis for a repository in which the enterprise's application-specific data, organization and function models can be stored. The ARIS architecture constitutes a framework in which integrated applications systems can be developed, optimized and converted into EDP-technical implementations. At the same time, it demonstrates how business economics can examine and analyze information systems in order to translate their contents into EDP-suitable form.
