Work collaboration is today normal practice in developing modern products. Engineering collaborative work involve a number of team members that need to share and exchange design ideas working with engineering analysis tools, such as mechanical computer aided engineering systems. This work presents a data mediation approach, using active database technology, which enables exchange of engineering information among distributed team members in a timely manner. The distributed data is automatically synchronised between different places using a database management system that support event-condition-action (ECA) database rules. Only the updates introduced at one location are distributed to the other locations, minimizing the information transfer and enhancing the performance. Members working at different locations can therefore interactively manipulate the same set of information at the same time
