A software design technique for client-server applications

Software design is the process of mapping software functional requirements into a set of modules for implementation. In this paper, a new design techn ique called the concurrent software design technique (CSDT) is proposed. CS DT extends software design techniques, which are based on structured analys is and design, by identifying independent concurrent tasks for implementati on in multiprocessing, multitasking and the C/S environment. A case study o n re-engineering a large legacy system, implemented on mainframes as a sequ ential system, to a CIS environment is presented next in order to highlight the benefits of the CSDT, Finally, this paper concludes with a comparison of CSDT with other existing approaches and the lessons learned from the exp erience with this technique.
