Study On A Web Service-based Software Reuse Model And Its Application

Software reuse offers a solution to eliminate repeated work and improve efficiency and quality in the software development. In the recent years, object-oriented and object-serviced technology has appeared and become a mainstream technology, thereby providing fundamental technology support for software reuse. Software reuse regains more attention in software engineering research and is considered a practical and feasible approach to solving the software crisis.Building a model of the four-layer architecture, analysis and aggregate software reuse method in every layer. In presentation Layer, many user controls and tags are used to get the code reusability and easily page rearrangement. In business layer, Web Service is used to realize the distributed loose coupling. In business component layer, Object-oriented system design is used, multinational and shared business interface and data structure that has little granularity, high extensibility and flexibility for system. In database layer, a method based on XML to implement data integration is given, a XML interface is provided in data layer, business logic layer and business component layer can access any data resources based on the uniform format. All this design used has solved the reusability problem that exit in traditional software development.Based on the research, through applying the result to practice on the design and programming of enterprise application by building reasonable System Architecture and using software reuse, testify the research's feasibility and validity, testify the research's feasibility and validity.
