Tuxedo Middleware Centralized Land Tax Collection And Management System Design And Realization

Among the construction of the local tax information system, the local tax collection-manage software system is central part, along with the information technology development phase is different, local tax collection software presents different characteristics, the early single computer tax collection system pattern and the pattern of tax collection system distributed various county working on their own way, already were unsuitable to the tendency that the central local tax collection pattern is developing to the wide range. the local tax department had to establish the central local tax collection software system in wide range .Along with central local tax software system has been established, the scope of application has been changed from original local area network environment to wide area network environment. Along with the network environment of application has been changed, transmission data through the long-distance network, has brought to the issues of the reliability and safety of the system, and the system response speed, etc. This paper is aimed at, during construction of local tax information system, the need to create large regional central local tax information system, to overcome the shortage of existing local decentralized systems; analyzing and solving the problems revealed from the two layer architecture prototype system actual running in the wide area network environments, during understanding customer needs, to design C/S three layer architecture central local tax system. First, in this paper, I analyze the present situation and the practical application situation of the local tax system, summary the problems and the insufficiency in the original system, analyze "Deadlock" problem of the database tasks revealed from C/S two layer architecture prototype system and the "hang-death" phenomenon of client trial running in wide area network situation, identify the causes and find solutions, then, design C/S three layer architecture local tax collection- manage software system based on the solution. Next, I describe concrete realization of the maintain subsystem associated with my work in detail in the paper, and some key technologies involved in the design. To solve the problem of stability and reliability revealed from instability of the wide area network. I use Tuxedo middleware as a middle tier in C/S architecture. Through the Tuxedo middleware buffer technology, system has been realized reliable transmission of data between client and server, and the question in the system which appears in the WAN environment has been reduced effectively.
