Model-Based Interoperability of Heterogeneous Information Systems: An Industrial Case Study

Integration of heterogeneous and distributed IT-systems is one of the major cost-driving factors in the software industry. We introduce a model-based approach for information system integration and demonstrate it on the industrial case-study of data integration between the Oracle database management system and the SAP R/3 enterprise resource planning system. Particular focus is on multi-level modeling abstractions, integration conflict analysis (automatic data model matching), semantic reasoning, code generation and tool support.
