Extending UML for Aspect Oriented Software Modeling

During software engineering process, designing software is one of the most crucial and volatile phase.In order to construct software, much of the design must be done in accordance with the requirements. Requirements have an impact on the design and design in turn has a severe impact on the construction or development phase. UML has been the design tool of choice for years with the dominance of object oriented technologies and object oriented design methodologies. Aspect oriented programming (AOP)is a new wave of thinking that builds on the object-oriented paradigm to resolve the cross-cutting concerns in software. Being an extension to the OO paradigm, UML needs to be extended to fit the new ideas that AO paradigm introduces. This paper presents extensions to UML for Aspect Oriented Modeling.
