Active technology in database management systems (DBMS) enables the movement of behaviour dependent on the system’s state, from the application software to a rule base in the DBMS. With active technology in database systems, the problem of how to design active behaviour has become an important issue. Modelling processes do not foresee support for design of active rules which can lead to conflicts between the event-condition-action (ECA) rules representing the active behaviour and the application systems, using the active DBMS. The unified modelling language (UML) is a widely used notation language and is the main subject in this project. Its features will be investigated to acknowledge to what extend UML modelling diagrams provide information that can be used to formulate ECA rules. To achieve this, two methods where developed. One of the methods was applied on use-case UML modelling diagrams. The use-case models were developed by means of reflecting a real-life organisation. The results from applying the method on the use-case models were that there are features in UML that can be expressed with ECA rules.
