Abstract:
This article discusses support for the Unified Modelling Language (UML) standard in Model Driven Architecture (MDA) style software development. There are described some of the weaknesses of the UML standard that software developers should know about, to take full advantage of this otherwise very good and desirable standard. Specifically, it is a hierarchy of object classes, which belongs to the basic concepts of the object-oriented paradigm. This hierarchy is considered well known, but in fact there are three slightly different hierarchies that fortunately fit well with the MDA philosophy. The problem is mainly that all these three hierarchies appear in UML in the same way, as if they were just one type of hierarchy. The article describes and explains these differences and suggests a refinement to the UML using stereotypes. The conclusions written in this article are a summary of the authors' experience of software projects for the international consulting company Deloitte and of university education.
