Business rules tend to change in the course of time influencing modifications in business supporting information systems. Unfortunately, business rules most often are embedded in the source code of software systems, poorly or even not documented, and implementation details are known only for the developers. The paper addresses these issues and considers a model-driven process for derivation of business rules from the models of existing information systems, providing supporting tools, and supplementing the overall modernization process.
