Research And Design On Province Centralized Host Computer Systems Of Post Electronic Branch Bureau

This paper research the scheme layout of province centralized project of Post electronic branch bureau, and taking Shaanxi Post as the object, using system analysis theory and the theory related to project management, design and realize the province centralized project of Shaanxi Post electronic branch bureau, through a large amount of analysis and calculation, layout and design the host computer systems.First, in the paper, on the basis of analyzing design principles and characteristics of the application system, the three-tier C/S architecture adopted by the system is designed within the paper, and focused on the interconnection with other systems.Secondly, through analyzing the centralized model of the network structure and lines of communication, then compare three kinds of branch bureau connect mode, determine the Shaanxi postal network building programme; according to the Shaanxi Provincial Post business and other factors, using server election aspects of theory, based on the industry recognized the relevant empirical formula (such as online transaction processing capabilities to measure : the TPC-C benchmark), analyze and calculate the host systems processing capacity, memory size and hard disk capacity to finalize the host system's configuration.Thirdly, according to the overall goal of the project, by using the project management theory, divides the project into specific stages of project implementation, clear the responsibility of the parties, and make overall implementation plan and contingency plan.Finally, the paper analyze the investment benefit, the social benefit and economic benefit brought by the project are great.
