Dos requisitos à arquitetura em linhas de produtosde software: uma estratégia de transformaçõesentre modelos

摘要

The tracking between models of the requirements and architecture activitiesis a strategy that aims to prevent loss of information, reducing the gap betweenthese two initial activities of the software life cycle. In the contextof Software Product Lines (SPL), it is important to have this support, which allowsthe correspondence between this two activities, with management of variability.In order to address this issue, this paper presents a process of bidirectionalmapping, defining transformation rules between elements of a goalorientedrequirements model (described in PL-AOVgraph) and elements of an architecturaldescription (defined in PL-AspectualACME). These mapping rules areevaluated using a case study: the GingaForAll LPS. To automate this transformation,we developed the MaRiPLA tool (Mapping Requirements to ProductLine Architecture), through MDD techniques (ModeldrivenDevelopment), including Atlas Transformation Language (ATL) with specification of Ecore metamodels jointly with Xtext , a DSL definitionframework, and Acceleo, a code generation tool, in Eclipse environment. Finally,the generated models are evaluated based on quality attributes such as variability,derivability, reusability, correctness, traceability, completeness, evolvability andmaintainability, extracted from the CAFÉ Quality Model
