UML sequence diagrams used to define basic interactions between objects at the level of method invocation while they are not well-suited for describing the complex interactions as they occur in multi-agent systems. In order to solve this problem, Agent UML is proposed based on UML2.0 by OMG and FIPA. Three extensions to UML are analyzed and an example is utilized to show the Agent UML sequence ...

Recently, aspect-oriented approaches have resulted in a tremendous impact on the processing of broadly scoped properties during the development of software systems. However, the weaving mechanism of these crosscutting concerns cannot be easily represented with the extant uniÞed modeling language (UML) notation at the early stage of software development life cycle. As an attempt toward the inves...

The Unified Modeling Language (UML) is a visual modeling language dominant in objectoriented software development. This language was adopted by the Object Management Group (OMG) as its standard modeling language in 1997. UML 1.x defines nine diagramming techniques: Class diagram, Object diagram, Component diagram, Deployment diagram, Use Case diagram, State-chart diagram, Activity diagram, Sequ...

The most important part of the testing attempts is the test case generation. Unified modeling language(UML) is the most generally used to describe design specification and analysis by both academic and industry. UML models offer a lot of information that should not be ignored in testing. Testing of software is a time-consuming activity which requires a great deal of planning and resources. In s...

This paper presents one proposal for teaching the foundations of object oriented programming using the Unified Modeling Language (UML) as one modeling language and Java as one object oriented programming language. Unlike other approaches where only two types of UML diagrams are used with the intention of transferring them to a codification (class diagram and sequence diagram, or class diagram a...
