Design And Realization Of Distributed Sales Management System Based On J2EE

With the trend of economic globalization, Information is playing an important role for enterprises worldwide. In order to improve the competence of enterprises themselves in marketplace, more and more enterprises have established the electronic commerce system. Sales and information management system is a quite important part of it. With the rapid development of Chinese economic and the fast expansion of enterprises' scale, sales architecture of many large-scale and medium-sized companies is composed of many sub-sale branches that distributed in different locations, and even overseas, Therefore, it exerts further signification to build distributed sales management system which contributes greatly to enhance the collaboration among each point of sales, reduce the overstock of volume, speed up the turnover rate of capital and accelerate the market reaction rate of enterprises.In recent years, the emergence of distributed component object technology has provided a powerful solution for the development of network software. Nowadays, distributed component object technology has already become a core technology in establishing the web service application framework and the components of software, and moreover, it shows strong vitality in developing the large distributed application systems, especially electronic commerce application system.At the beginning of this paper, the background of task and technology basis is involved. After that, the ultimate principles of the three typical distributed object technology DCOM, CORBA and EJB is expounded, and then the similarities and differences of these three typical technologies are compared. As the following, the J2EE platform and EJB Distributed Object Technology are analyzed deeply and their infrastructures, components, designing issues and even deployment requirements are researched. In the end, the advantages, which based on the J2EE infrastructure and the EJB distributed component technology, in the construction of the management in information system is discussed.Sales information management system is a main component of agriculture by-product exchange information platform. Based on the requirements analysis of sales management system, which is according to the operation flow and centering on the finance, The distributed sales management system is established. This system can combine the sales information of different branches effectively and help enterprises to manage various operations rapidly and effectively, including the management of sales, allotting on plan, stock and account receivable etc. It can also control every link of business activities and improve the ratio of capital utilization and the speed of balance, thus, it makes sure the characters of high efficiency, timing, safety and intelligence in management. In the developing process, the system combines both B/S (Browser/Server) architecture and C/S (Client/Server) architecture. The C/S architecture is adopted among different companies and internal of company as well; while the B/S architecture is used for the information querting and supervising. Moreover major technologies and key problems of system architecture,database design,EJB component and cell test are described and analyzed, which has referenced value for the development of similar systems.
