Aspectos iniciais modelados com uma extensão da SYSML

Abstract

Aspect Oriented Programming has been proposed in order to handle crosscutting concerns in an ecient manner. Initial proposals in this area have been applied to the source code. Subsequently, aspects were considered to be implemented in other phases of software development such as Requirements Engineering and Software Architecture. There are several advantages in identifying aspects at the requirements level and architecture level such as detecting conicts of interest, improving the requirements modularity, reducing costs of software maintenance and preserving the notion of aspects in software development process ensuring traceability. Therefore, the purpose of this work is to develop a model to represent aspects at the requirements level and the architecture level. The requirements model denes the activities of identication of aspect requirements, both functional and non-functional, separation and composition of aspect requirements and identication of conict between aspect requirements. Since dierent stakeholders need to view the system from dierent perspectives, the architecture model allows to represent dierent views considering the representation with aspects. The proposed views are structural, use case + requirements and development. Compared to other analysed approaches, the proposed models in this work represent important characteristics that others models do not represent, such as maintaining traceability of aspects between requirements and the architecture level. In order to represent the models, extensions to the SysML modeling language were proposed.
