Design And Implement Of Web-Based Purchase-Sales-Inventory Management System

The data of the small and medium-sized enterprises'purchase, sales and stock information is extremely huge, and then data statistical analysis is difficult. Therefore, developing one suitable management information system is very necessary, which includes enterprise's purchase, sales and the stock information.Before the system is developed, the author studies and analyses the requirements. The main contributions of this dissertation are as follows:1. By obtaining customer information through various channels provided by enterprise's purchase-sale-inventory system, customer needs can be understood quickly and accurately, as a result of which sale efficiency can be improved and revenue can be enhanced.2. The enterprise's purchase-sale-inventory system can provide various forms of communication channels between enterprise and customer and the consistency and continuity of the data therein has already be secured. Utilizing these data, the sales department can make quick and correct response in accordance with customer needs so that the customers can recognize and be willing to maintain the effective communication channel with enterprise while being satisfied with the product purchased by him.3. Through the classification and categorization of customers as well as the analysis upon the characteristics of each group of customers, the blindness in the formulation and execution of marketing and promotional strategy can be avoided and time and capital can be saved.This system has the following two advantages. Firstly, it establishes the manage information system to streamlize business processes and information flows so as to further improve their management, in addition, with its aid, all the managers of functional departments can cooperate to enhance the overall level of management. Secondly, with human, physical and financial resource available, this MIS helps industrial enterprises to demonstrate their superiority, to expand their market-sharing rate and improve their competitiveness. The designing, developing and implement process of the Purchase-Sales-Inventory Management System is expatiated in this paper. The system is developed under .NET platform that provides multiplayer distributed application model, component reuse, consistent safe model and flexible affairs controlling. It will greatly meet the System demand. The .NET platform promoted by Microsoft is to simplify the development of applied program under the third generation Internet's distributed environment, and based on the open standards and the protocols of the Internet, which is built also for the realization of isomerism language and the highly interactive. The .NET development platform includes .NET Framework and .NET Development tools. The platform makes the development of the client side graphical interface program based on Windows and applied program based on Web is easier.
