Anand V. Bhatnagar,Yashoverdhan Vyasg families of UML languages. Actions are defined as computational procedures with side-effects. The action semantics are described in the MML style, with model, instance and semantic packages. Different actions are described as specializations of the basic action in their own package. The aim is to

It is generally recognized that without a simple, clean and intuitive theory of how metamodel levels are created and related to one another, the UML2.0 vision of a coherent family of languages with a common core set of concept

This paper argues that although MML takes a metamodeling approach to language definition, it cannot be described as strict metamodeling. This has significant implications for the nature of the metamodel a

In this paper, we extend UML activity diagrams by introducing timing constraints so that they can be used to model real-time software systems, and give the solution for timing analysis of UML activity diagrams. We give th

UML sustains many aspects of software engineering; however, it does not provide explicit facility for writing queries. It is crucial for any such query language to have, at least, the expressive power of Relational Algebra, which serves as a b

Sherli Koshy-Chenthittayil,Elena Dimitrovamatically deal with business rules when building object-oriented applications. We investigate how OCL constraints can be handled in database applications as one of the most important kind of business applications. Based on our OCL toolset prototype and earlier research work we particularly experimen
