| In the field of distributed application, most traditional architectures form a closed system by using a variety of technologies which are tightly coupled and independent of each other. It is lacking of compatibility, effective interoperability and reusability which make it difficult to expand and limit its further development and application.As the development of the software technology and the appearance of the Web Services, the new method to develop the software system was put forward to. The new method is called Service-Oriented. Through the means of the design scheme adopting the SOA framework, the coupling among systems can be reduced to the maximum extent and the software reusing can be improved, therefore the remaining system can achieve a better integration to upgrade its flexibility and expand ability. It will change the traditional ways of building, developing and disposing the application systems and will become more effective solutions for the complicated IT circumstances.But now, the researches about design methods on Web Services based on SOA has showed many insufficiencies. This thesis started with introduce of theories on SOA and Web Services. Do research on the architecture, the principle and the method of design of the Service-Oriented architecture technology. Under the guidance of these theories, Following these principle, this thesis setups an architecture based on SOA, which is composed of client tier, based on the Object Orient Analysis Design and the thought of software delaminating, elaborating the method of inviding tier, the function of tier and the design method, etc,based on the popular distributed compute platform..At last, realizing an example, named the Student's Information Management System. And design a model of an appication system based on SOA through practicing. Combined with the application system example, the analysis, design and implementation of the system are all deeply discussed in this thesis. |
