Business Rules and Services in the Context of Model Driven Architecture

Nowadays, the relationships between people and organizations are subject to fast changes. This paper proposes a model for flexible business rules modeling in the context of model driven architecture from OMG - Object Management Group. Considering that some business logic portions are quite volatile and susceptible to changes and other portions are quite stable and less susceptible to changes, the model can capture business changes and quickly implement them into computational systems. The volatile portions are externalized as business rules and the stable portions as SOA based services. Business rulespsila facts and conditions are linked to services, which are discovered in the business rules development or maintenance time. Business rules are modeled according to OMGpsilas semantics of business vocabularies and business rules metamodel.
