TítuloA PROCESS MODEL FOR SPECIFYING SYSTEM BEHAVIOR WITH UML topo da páginaAutoresAna Moreira, FCT/UNL João Araújo, FCT/UNL topo da páginaResumoSoftware development projects grew a reputation for poor quality. This situation is in part due to the lack of appropriate mechanisms to identify and express functional requirements in a flexible yet rigorous fashion. UML is a standard modelling language that is able to specify applications in different levels of abstractions as it provides a wide range of notations. Among them, we have collaborations that serve to realise use cases, a powerful abstraction concept. The behaviour part of a collaboration is rendered using sequence or collaboration diagrams. However, the lack of abstraction and refinement mechanisms compromises the understandability and modularity of a specification. In general, we can say that abstraction and refinement mechanisms help obtaining a more maintainable system. Our aim is to provide abstraction and refinement mechanisms accomplished by proposing a modelling process.topo da páginaPalavras ChaveUML, sequence diagrams, collaborations topo da página |
