Design And Development Of Yanzhou Coal Company’s Plan And Statistical Information Management System

With the rapid development of computer network and scale expansion of managementinformation system, the complexity of computer software has been increased. Besides, thepart which the software system structure plays in the process of software design and softwaredevelopment becomes more and more important. How to construct efficient and safeenterprise application system fast has become the focus in IT industry. The application basedon B/S multi-tier architecture is completely oriented to enterprise application system.Compared with the traditional system structure, it has the engine architecture of informationsystem and it is completely oriented to Internet. System performance can be scaled. Systemfunctions can be scaled. The system has many features, such as convenient maintenance,strong scalability and strong strength of enterprise application and so on. At present, more andmore enterprise application systems choose multi-tier architecture application system to dealwith various needs arising in the process of enterprise developmentThe author proposes one kind of development architecture based on B/S multi-tierapplication software after doing deep research on traditional3-tier structure. This architecturedivides the traditional3-tier model more carefully. In the design of presentation layer,interface layer separates the structure, the style and the behavior from each other. The HTMLtag is only responsible for carrying content. CSS is responsible for bearing style. JS isresponsible for the norms of behavior. User logic layer is used to process the control logic inpresentation layer. Data exchange layer is responsible for processing the data exchangebetween the presentation layer and business logic layer. In the business logic, basic public layer includes all the public parts that will be probably used in business-specialized logic andsupporting logic, offering support for business-specialized logic and supporting logic.Supporting logic provides global data that the whole system needs. Business-specialized logiclayer realizes the special business required within the field. The data access layer providesdata services for the business logic layer and shield the differences between data sources. Thearchitecture accurately applies the modularization and the thought for object-orientedsoftware development to the construction of information system so that the reuse of softwarecodes with different levels is realized.Based on the multi-tier architecture, this thesis does deep research and analysis on theplan and statistical management business of Yanzhou Coal Company. It establishes systemfunction model and data model according to the actual business demands and completes thedesign and realization of Yanzhou Coal Company· plan and statistical managementinformation system (YCPSS).The actual operation results indicate multi-tier architectureadopted in this paper is correct and very effective. It not only makes the scheme become clearand well-organized, but also lays good foundations for system expansion in future.
