The Design And Implementation Of Lanzhou Long Xin Electronic Commerce System

This text studies and achieves a kind of design and structure of electronic commerce system. First, the thesis did simple contrast analysis to the development characteristics of electronic commerce system domestically and internationally, and then made a brief introduction to the technics and skills what I have adopted. As to the requirements analysis period, by using the possibility analysis of the economics, technics and practice, the article proves that this system is feasible, and makes a refined processing to the system according to what the company actual needs. I make detailed analysis to the User activities, Using case, Entity Attribute and Relationship of administrators, visitors and members of different roles as well as to the Date-flow when use the system. Which provide plenteous theory basis? In the design and implementation phase, the article makes an essential design from the principle of overall design, from the system structure and its function module, defines each field and attribute in the system database, clear of relationships among each form, and provides different users with different functions. Thus, the System achieved different function modules such as shopping interface, shopping cart, security management of the role and Online secure payment and so on. In the design of user shopping function module, the system guarantees superior using functions in the process of it. During the progress of achieving the managemment functions. By using the layered structure designing thoughts, based on guaranteeing the smooth execution of various functions and procedures, so that the system has good portability and scalability.The paper finally tests the application environment of system. Testing results show that the system and its function could perform normally, the interface design is complete, and achieves the expected design goal. The development and application of System provides the corporation with informational marketing channels, and also improves informational competitiveness of the company. What is more, it standardized the teaching design of vocational software design professional in colleges, and also improves the teachers’ and students’ practice ability.
