Research & Development Of Distributed System Based On The Web

On the bachground of Information Technology (IT) this thesis is focused on the research of the theory, structure and application of distributed system based on Web, which is based on the design and implemention of the Salary Pay-Off System. The practical meaning of topic selecting is important.The distributed Application bring into a new concept of design and extension.Firstly, the development of distributed system is introduced and the analysis and comparison are discussed in detail. The distributed system based on Web will be the developing trend of distributed system. Then the theory and application are analyzed deeply. The differences between distributed components which are used widly are investigated.Secondly, the design method that combine structural and object-oriented designing is proposed. The method is based on the author's experience in work and the idea of evolution model and spiral model. The design mode based on public resource base and reuseable component is brought forward also.Thirdly, the paper bring forward the structure and the flow of Salary Pay-off System according to the demand,at the same time .analyses the problems of the formerly Salary Pay-off System and the customer positioning of the system,and builds the data analysis model of the system. At last,the paper summarize the database design method,and point out the principle in database design.
