Research And Application Of Post Business Letter Processing System

Business letter gets energetical development in the postal trade at present, but use the postal business letter process system not to meet the actual demands at present. This text develop , for background , introduce whole development course of software with Shandong postal business letter process system, have carried on detailed analysis to the necessary technological question while developing especially.This practice is in accordance with the order after the first theory started. First introduced in the system development process required related technologies and systems used in development platforms and tools; Then apply these techniques and methods for the analysis and design of the entire system, the system finally gave specific date.In the technical part of the introduction, first introduced the system architecture development of a detailed analysis of the three-tier structure. Based on the need to design development, introduced object-oriented software development methods and structures of the two. Database design introduced in the analysis of data management technology development process, focused on the development of database management systems and design steps. Finally on the system used in development platforms and tools introduced :Server operating system adopt unix, the customer sysetm adopts windows; The database system adopts oracle8i; middle software adopts bea tuxedo; Analyze in the demand stage adopts UML software modeling language.In the analysis and design parts, the first dealing with the operational procedures for postal business Letter analysed, and the planning system, introduced to the system, and given the application of UML use cases related maps. In the three-tier structure of the model system used, given the logic of the system by,for the deployment of various services, designed to achieve a specific way. Business Letter system for the analysis of database requirements for data storage model given three of the programme, a specific analysis, distributed storage model a specific date. Final design of the database structure.In the realization of part of the system, the main responsibility of a specific synchronous system analysis and design modules, given the procedures chart coding to achieve a specific function. Since 2005 the system of postal operations in Shandong has proved reliable system operation, the results are satisfactory, very good to meet the needs of business development, achieved the desired results.
