Abstract: Aspect-Orientation and Object-Orientation complement each other in a number of aspects. Hence, it is imperative to investigate level of adopting Unified Modelling Language (UML) by the Aspect-Orientation. This study employed a systematic literature review to examine the approaches of Aspect-Oriented UML (AOUML). The rapid growth of complexities of systems, of late have eventually paved way for the emergence of new concerns. In fact these new concerns have cut-cross other concerns and core classes in the system by their nature. Therefore, it is crucial to focus on the concept of crosscutting concerns (Aspect), throughout the whole development life cycle, as they are accountable for generating, disseminating and interweaving depictions. The scope of this study is to depict and examine the current state of art of Aspect-Orientation modelling using UML. The UML diagrams have been implemented on the top of Object-Orientation concepts, it has not been meant to be used to model Aspect-Orientation. Thus, the motivation of this study is to propose a complete tailored formwork that represents Aspect’s constructs using all UML diagrams based on AspectJ constructs. The objective of this present study is find out the shortenings, lack of support, advantage and disadvantage of the existing well-known approaches of Aspect Modelling based on a carefully selected, evaluation and compression criteria. The examination and analysis have revealed that there are some deficiencies of Aspect representation in the early stage of software development, while using the existing UML. We have concluded that extensive research has to be carried out, for us to get a complete comprehensive framework modelling approach that covers all UML diagrams, rather than just a few, moreover we suggest that the assumption of modelling extensions have to depend on a reliable base.
