Modularização com orientação a aspectos de frameworks desenvolvidos com linguagens de padrões de análise

Abstract

GRN (Gestão de Recursos de Negócio Business Resource Management) pattern language provides a set of patterns in analysis level to support the development of applications which deal with rental, purchase, sale and maintenance transactions of a good or service. GRENJ-OO is an object-oriented (OO) application framework built to support the instantiation of Java applications in the GRN domain. GRENJ-OO instantiates applications that include in their architecture all framework variabilities. The units of this framework, which implement each GRN pattern and their variants, are highly coupled between them, because there are concern tangling and concern scattering related to each one of those patterns. So, the aspect-orientation (OA) techniques were used in each pattern to minimize those problems and a new framework version was obtained, called GRENJ-OA. The improvements of separation of concerns, the coupling reduction, the cohesion increasing and the reduction of the number of lines of code of the majority of the patterns implemented in GRENJ-OA was the result reached after performing a quantitative evaluation based on separation of concerns, coupling, cohesion and size metrics. From the approach used to modularize this framework is introduced the Framework Product Line concept, that consists in a product line which their products are frameworks instead of software applications. From the GRENJ-OO modularization was also possible to extract a process that can be applied to modularize frameworks. This process aims to transform a framework in a Framework Product Line.
