The Analysis And Design Of Supermarket Uncertain-Demand-Commodity Procurement System

With the rapid development of information technology,especially the improvement of database technology,visual designer,intergrated development environment and other technologies,many enterprises have tried to strengthen their competitiveness through combining traditional management and operation modes with Internet technology.As a major place for people's daily purchasing,supermarket contains and manages many different kinds of goods with fast circulation.Currently,many large supermarket have adopted commodity procurement systems with C/S mode,but it can not meet the demand of low cost and high efficiency of most small supermarkets.While,at the same time,the changing improvement of management and the inoreasing demand for commodities also promote the design of commodity procurement system toward surpermarket.It has become an inevitable trend to implement supermarket-oriented commodity procurement system from the design of commodity information management to commodity procurement.This paper completes a whole analysis and design of commodity procurement system;realize several functional modes ranging from user login,information query,information maintenance,generation and maintenance of purchase order to code maintenance and soon,meets the requirements of different system users by requirements ananlysis,case analysis,function analysis and sysrem design,implementation and testing by fully considering the perspective of user' demand.In this paper,we realize the man-machine interactive interface and the design of muli-layer architecture though high-level Java progromming language,which not only meet the functional requirements and non-functional requirement of the system,but also enhance the maintainability of the system;By comparing the advantages and disadvantages of kinds of database,this paper uses the My SQL database,using relational database to implement some basic operation,such as increasing,deleting,modifying and querying information of commodity and uses.This paper first illustrates the system research background and significance,research status,research and methods;besides introduces the use of Java programming language and database technology;then implements demand analysis,case analysis and function analysis on the system;next completes the design of system,mainly including database design;finally includes the system implementation and testing,equivalence partitioning is mainly used in the system texting.At present,the design of this system has been completed,and users reflect generally that good human-computer interaction interface,simple and convenient operation can satisfy uses' requirements of commodity procurement system.And information maintenance of the system can be done by a small amount of users,which can not only reduce the operation cost of enterprises,but also enhance the execution efficiency;besides,the secure login function can enhance the security of system;using database technology not only has the function of data backup,preventing data loss and saving physical storage space,but also can maintain data consistency.
