Abstract

Object-oriented modelling is used in a growing number of commercial software development projects. However, the plethora of approaches and corresponding CASE tools still prevents corporate users to migrate to object-oriented software development methods. Against this background the recent efforts of the Object Management Group (OMG) to standardize objectoriented modelling languages seem to promise substantial benefits: Not only will a standard allow to easily port a model from one CASE tool to another, it will also protect investment in training. In addition, it is a prerequisite for standardized business object models which - in the long run - may substantially improve the economics of developing and maintaining corporate information systems. Nevertheless there are objections against a standardization at present time: It is questionable, whether the state of the art in object-oriented modelling is mature enough to allow for standardization. Furthermore standardization holds the risk to discourage further innovations. In order to
