Research And Design Of Software Architecture Based On Requirement-Driven

The software architecture is becoming the important research field of software engineering gradually, and has gotten the general approval of the industry as a discipline finally. Under the software development approach based on component and architecture, basic change has correspondingly taken place too in the software development. Software development was not "algorithm and data structure" again, but "component development and assemble by component based on architecture". The software architecture begins to appear in the course of software development as development files and intermediate products.On the basis of introducing concept of software architecture and which designing and description methods, this paper put forward a kind of new architecture description method and design method, which not only emphasized the function demand but also required developing a group of architecture demands emphatically. Otherwise, it built the software architecture progressively with iterative technology. And adopt UML mechanism that developers are familiar with to describe the software architecture. That makes mapping more closely, and can get support from commercial tool.Following, on the basis of studying the three-tier architecture based on components which was already be used widely, we introduce the concept of Web Services and WSBTA, a new hiberarchy architecture model based on Web Services was brought. WSBTA developing the traditional three-tier architecture. At last, we design an application model under the WSBTA and combine with a Web Information Publishing Builder, we make some appraisal to the architecture.
