Each Zhongyan Industrial Company Sales Management System Based On J2ee Design And Implementation

With the popularity of the Internet in the global information technology, theenterprises informationization is the trend of world development, reflected in theeconomic growth in the roles is particularly significant demand for the applicationsystems based on Web to meet more complicated requirements in the marketingenvironment, and meanwhile with short research&develop period. For the medium andsmall size enterprises, it’s a problem on how to promptly develop a Web applicationwith scalability, availability, reusability and security. Based on the realistic situation, byresearch on current multi-level systems and the integration of third party analysisframework in order to meet the J2EE specification, a generic and dexterous Webapplication architecture will be designed in this thesis.Along with the rapid development of Chinese tobacco industry, tobacco enterprisesare facing a series of management problems. Firstly, due to the needs of development,the management environment takes change, the former provincial tobacco bureau hasbeen divided and set up an independent provincial industrial corporation.Secondly,thecurrent types of software were developed by different software companies with differentcodes and design systems, the problem of Information Island has become serious andsystem integration is very difficult.Thirdly,the design of existing software couldn’t meetthe needs of management reform and enterprise modernization. Thus Tobacco systemadministrator urgently need for a management information system which is appropriatefor their own management to acquire information rapidly, to make strategic decisionsand optimize the allocation of resources which can promote the healthy development tomaximize the role of existing equipments, raw materials, technology and manpower,therefore to operate with economic efficiency of enterprises and enhance marketcompetitiveness. The system is tailored to China tobacco enterprises based on the J2EEstructure according to the needs of the development of the information centers. Thissystem integrates the value of the original system, and adds other auxiliary functionsthat can not meet the existing real business needs.Web Application development based on MVC mode provides a theoretical basis for the design and development of this thesis. MVC mode could overcome the inherentlimitation of traditional web application developing method. Its main advantage ofseparation of display logic and transaction logic enable it to satisfy the increasing needof web application design. Therefore, based on J2EE application development model ofWeb design and development is the theory of our management system. Meanwhile, inconsideration of users’ non-functional needs as much as possible, it tries to make systemoperation and understanding easy, which intensifies humanized and individualizedphilosophy. At the same time, according to specific business characteristics and users’requirements, this system adopts B/S structural model and SQL Server2000data base atbackground, which connects provincial bureau and each municipal bureau by TCP/IPprotocol through existing computer network resources and centralized storage database.Experiment and practice has testified that this new framework improves workingefficiency and R&D period in development to meet the system scalability, availability,reusability and security, based on this framework, it’s also suitable for the medium andsmall size enterprises benefiting from it to rapid develop secure Web application.
