Modern information systems (IS) have widely penetrated into many kinds of social activities by helping to perform business operations and to interact with the surrounding environment. Since business is under jurisdiction of government’s laws, business mission and polices, guidelines and other documents, these business restrictions should be implemented in a business supporting IS and effectively managed. A business rule approach is widely accepted in IS community as a way to express different types of business restrictions and constrain operation of components of an IS. Nowadays, there are number of methods and approaches to extract, define and implement business rules. However, there is no a commonly accepted standard for their modelling. In this paper an ontology-based method for business rules modelling and implementation in the software of IS is presented. It allows to automate the transformation of rules from ontology to the software level and to reduce the cost of rules implementation and likelihood of errors. A case study is described in the paper also.
