Object-Oriented Database Prototype as a Model Execution Engine for Executable UML

The concept of executable modelling, as outlined by the MDA approach, is not very common in the area of business software using databases. One of the reasons is certainly the increased complexity and heterogeneity of such software on its target platforms. Another reason is a weak support for such data-intensive software from the modelling solutions related to UML. In this paper we present the issue of extending those capabilities within the boundaries of standardized OMG specifications, and describe our practical experience with building a model execution engine supporting them, which is based on the ODRA (Object Database for Rapid Application development) experimental ODBMS platform. The potential results are twofold. Firstly, this allows to assess the precision of UML specification from the point of view of database languages design state of the art. Secondly, this helps us to check, how approachable our system can be for the users familiar with the object-oriented notions of OMG specifications.
