Modeling Of DSSA In Basiness Supply Chain Based On Software Reuse

Currently software reuse is becoming an effective method for solving software crisis, and it focus on basic model(COM/DCOM,CORBA,EJB), developing component, establishing and manage component library, software architecture and so on. Large number of practice in software reuse indicates that it is difficult to obtain the software architecture adapting to all the application systems for its high reuse. At the same time, it is possible for the software reuse in specific domain because of the same speciality of a domain. Recently domain engineering gets great progress, and it includes the reuse of domain knowledge, domain requirement, domain modeling, documenting and so on. It is a more efficient and important method of software reuse by reusing DSSA.We investigates some mature application systems in the domain in detail, such as JUSTSOFT.CHINA, GBEIUN GoEasy ERP and analyze the common and difference of a class of application systems by using FODA. By this process, we can establish domain model and abstract DSSA satisfied the function of business enterprise SCM and describe them in detail.We apply these reuse products to the development of medicine enterprise SCM. In the process, System analyst can acquire the requirement of application engineering by domain model as developing it, and then constructs the systems' architecture based on the traceability between requirement and DSSA. Through these steps programmers can develop the application system quickly. Compared to the development method currently, it is expected to search after a development method of application system that is from top to bottom based on software reuse. The reuse products (domainmodel and DSSA) have the value of requirement reuse and design reuse andwe can improve the efficiency of development.
