| Abstract: | There are several SDL methodologies that offer full system life-cycle support. Only few of them consider software reuse, not to mention high-level reuse of architecture and design. However, software reuse is a proven software engineering paradigm leading to high quality and reduced development effort. Experience made it apparent that – beyond the more traditional reuse of code – especially high-level reuse of architecture and design (as in the case of design patterns or frameworks) has the potential of achieving more systematic and widespread reuse. This paper presents the SDL pattern approach, a design methodology for distributed systems which integrates SDL-based system development with the pattern paradigm. It supports reuse of design knowledge modeled as SDL patterns and concentrates on the design phase of SDL-based system development. In order to get full life-cycle support, the pattern-based design process can be integrated within existing SDL methodologies. |
