Data Integration and Interoperability: Towards a Model-Driven and Pattern-Oriented Approach

Data integration is one of the core responsibilities EDM (enterprise data management) and interoperability. It essential for almost every digitalization project, e.g., during migration from a legacy ERP resource planning) software to new system. One challenge incompatibility models, i.e., different systems use specific or proprietary terminology, structures, formats, semantics. need be interchanged between systems, often complex conversions transformations are necessary. This paper presents an approach that allows engineers experts models patterns in order specify integration: it based on such as ER (entity-relationship) diagrams UML (unified modeling language) class well-accepted widely used practice. Predefined combined (applied) model level leading formal, precise, concise definitions conversions. can then executed (via code generation) so manual implementation not The advantages existing reused, standardized lead fast results, specifications executable easily maintained extended. An example transformation elements relational object-oriented structures shows Its focus mappings relationships.
