【摘要】 本论文以IT行业为研究背景，结合工资统一发放系统的设计和实现，研究了基于Web的分布式应用系统原理、结构和应用，在选题上有重要的现实意义。 分布式应用引入了一个全新的设计和扩展概念。本论文介绍了分布式系统的产生与发展，对几种常见的分布式系统的机构进行了详细的分析比较，指出基于Web的分布式系统是分布式系统发展的方向。通过对基于Web的分布式系统的体系结构原理及其特性的深入剖析，提出了采用结构化与面向对象相结合进行系统设计的方法。文中还研究了分布式组件技术的特点，分析对比了不同组件的工作机理和应用方法。重点论述了基于Web的分布式应用系统的设计方法和流程，给出了基于公共资源库和可重用构件的设计方式。设计实现了工资统一发放应用系统，根据其业务流程对系统用户进行了定位，建立了系统的数据分析模型，选择相应的开发平台与数据库管理系统，设计实现了基于Web的分布式工资统发应用系统，解决了以往工资发放中的诸多问题。同时详细阐述了数据库的设计方法和对象模型的建立过程，并指出在数据库应用系统中应遵循的规则。更多还原

【Abstract】 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.更多还原
