Business rules in a service development and execution environment

In the current Web based enterprise systems the need of changes in these systems happens in periods shorter and shorter. Considering that some business logic portions are quite volatile and susceptible to the changes and other portions are quite stable and less susceptible to the changes, this paper introduces a model that can capture business changes and quickly implement them into computational systems. The model includes an approach for fast development and execution of services considering that the volatile portions of business logic can be externalized as business rules and the stable portions as Web services. It is proposed a framework for Web services composition based on business rules and service ontology. The framework provides support for business rules definition using a friendly language to the business analysts, for Web services discovery in the business rules definition time, and for making connection between the business rules and Web services in the service execution time. Business rules are modeled according to OMG´s SBVR metamodel.
