Enterprise resource planning (ERP) systems consist of many software components, which provide specific functionality. As ERP systems become more complex, the financial expenditures that are associated with the application of such systems dramatically increase. Furthermore, ERP system development of nowadays is product-oriented and coordinated by only one instance at any one time. Consequently, each product has a separate data model, which is the basis for the integration of various types of business applications. Based on this fact, the selection of the covered functional enterprise sectors as well as the implemented functions is controlled by the respective vendor, too. Thus, enhancements and modifications of the standard software product are incumbent upon the software vendors. A cross-vendor standardization of data models for ERP systems and the establishment of unified architectural model, however, would change this situation. The new idea is to develop a novel ERP system architecture, which facilitates an overall reusability of individual business components (BC) through a shared and non-monolithic architecture based on Web services. The presented approach uses Web services to wrap up ERP components that are provided within a distributed system, which appears as an ERP community and serves as a vendor-independent platform.
