Research And Development Of Chengdu Railway Bureau Of Party And Government Management System Based On RIA Framework

Party and government management system in Chengdu Railway Bureau is based on Rich Internet Client(RIA),and the technology of RIA is widely applied in large state-owned enterprises.This technology has become one of the most preferred technologies for many large information management systems due to its advantages and maturity of the technology.Meanwhile,in order to improve the efficiency,a search function is usually required in large-scale systems.We apply RIA to develop a multi-user and multi-functional application system.Traditional information exchange in enterprise suffers from a critical problem of efficiency.According to the analysis of RIA and search technology at home and abroad,this thesis discusses the technology of Extjs,Lucene and Apriori in detail.Chengdu Railway Bureau party and government management system has been developed with J2 EE to simplify the work of staff in railway sector.The main works and results of this thesis are as follows:First,the thesis proposes the requirements of Chengdu Railway Bureau party and government management system,including functional requirements and performance requirements.According to the requirements,an overall design and a detailed design of the management system has been proposed.In addition,we invest a lot of efforts into the module of Commission for Discipline Inspection and the global search module.Second,we implement the system to fit the user's requirements.Furthermore,the important processes in the development are highlighted.Third,a new framework is putted forward to reduce the code redundancy and improve the development efficiency.The development process is optimized through mapping one data to multiple pages rather than only one page.Fourth,we add the initial letter query function for pinyin,which is seldom supported in traditional software.The analyzer of the system is customized,and the query interface is rewritten for pinyin,thus ensuring that users can query correctly to avoid the misoperation.In addition,in terms of sorting of the query results,the Chinese query uses the traditional method,while the initial letter query uses the Apriori algorithm to improve the user experience.Fifth,we test both the function and performance of the Chengdu Railway Bureau of party and government management system.Furthermore,the thesis conducts the analysis of performance over traditional Chinese keyword query and the Pinyin initials query,and then summarizes the running status of single user and multiple users respectively.
