The Desgin And Implementation Of Transaction Processing Subsystem In The National Center Postal Convenient Service Station System

In recent years,with the continuous development of social economy,the service demand continues to increase,and the postal service is in urgent need of changing to adapt to the development of the era and customer demand.Although the service of China post has improved to a higher level,the people's material and cultural needs is growing.Under condition of the current economy market,the gap between the needs of general public and postal services should not be ignored.Especially for the existing Postal Convenient Service Station System,it has many advantages,but its disadvantages are equally notable.The ability for fast promotion to unified business is poor.It cannot support the whole of the country joining chain access.Besides,it is insufficient for sharing advantages among the integration of business resources,channel resources and data resources.The current Postal Convenient Service Station System cannot implemente effective group control.Therefore,how to build a national center for Transaction Processing Subsystem for the Postal Convenient Service Station System is urgent needs to solve.In this paper,the Postal Service Station has been built for the convenience of the central system of the central system to carry out the implementation of the systemFirst,this paper introduces the key technology involved.The middleware system back-end is using a Tuxedo middleware.The paper introduces the functional framework of Tuxedo.Notice that there can be mention of the communication architecture and mechanism.Besides,the application and implementation and practical application on the parameters and configuration are introduced one by one.The system use Oracle as the database which includes the composition and characteristics and declare how it is work.Secondly,in this paper,the Transaction Processing Subsystem part has carried on the detailed design and concreted implementation.Before the detailed design,the requirements modeling on Transaction Processing Subsystem has been completed from two aspects of the functional requirements and non-functional requirements analyses its expected demand.After the requirement analysis,in the stage of detailed design,due to the paper mainly lies in the demonstration subsystem back-end processing functions to achieve,at this stage in the description framework based on the function of each module respectively the concrete design and corresponding to the backstage database design,finally according to each module selects each have a representative of the specific business to complete the transaction processing,the realization of each module of the subsystem.Finally,this paper completes the test and analysis on the system.The test includes functional testing and stress testing.Selection function test Transaction Processing Subsystem representative transactions in each module design test cases respectively,using the way of test cases described the testing process of each module.According to the content of the test case frame type a description of each module of the test environment,use object,test process,expected results,and finally the actual test.Then,the paper also describes the project test team to carry on the entire system exchanges of pressure testing and validation work in order to demonstrates the feasibility of design and implementation.
