Abstract


As information technology continues to evolve and the information management requirements of the pharmaceutical enterprise from State Drug Administration Department continue to increase, the information technology promotion of the pharmaceutical industry is imminent. Now information systems in many medium and large pharmaceutical wholesale companies already have a considerable size, at the same time, business functions of the systems continue to improve, .However, with the innovation of the drug regulatory requirements from the regulators and changes of management strategies, the information systems often need to be adjusted according to actual situation. Therefore, the establishment of information systems must have high scalability.This issue is put forward to solve the problem of high development and maintenance costs, achieve high scalability and security in establishing the information systems of wholesale pharmaceutical companies. The information system is based on the three-tier C / S mode structural system. Separately package the business logic on the application layer, independent of the client and the database, to increase the reusability of code. Meanwhile, in order to achieve a strong expansion of the application layer, divide the business logic into multiple business objects creatively, and be packaged.Thesis begins by describing the background and significance in researching enterprise ERP information systems, then indicates the research objectives and content, specifies the research methods and the technology roadmaps. Then presents the foreground and background environment development tools and the language development environment required in developing ERP information system .In the next section, the thesis elaborates the needs and goals in the system designment, indicates six design principles and six component modules,analysis business process of the system. Then the thesis describes the detailed design of the system that divided into six major modules as well as the design of the database based on E-R diagram .Finally, the thesis describes the achievement of the main function code in the system and specific test programs as well as test results. The information system uses a clear hierarchical division and a relatively independent modular implementation. Thus, the system has many advantages such as good scalability, low development and maintenance cost and good applicability.System put into operation with favorable results, greatly reduces the complexity of personnel billing operations, inproves the efficiency of warehouse delivery. also clears the company’s appraisal system, and standardizes the company’s procedures and management systems.
