The Design And Implementation Of Management System In QD Supermarket

The development of medium and small chain supermarket is very convenient for people's daily life,but after China's entry into WTO,foreign large supermarket enterprises begin to enter the market,which makes it urgent to improve their competitive ability by means of information technology.This paper mainly takes the domestic QD chain supermarket as an example,through the analysis of the specific operation status of the QD supermarket chain,to carry out the design and development of supermarket management system which is suitable for the management of QD chain supermarket.In this paper,the design and construction of QD chain supermarket management system based on software engineering theory is studied in this paper.First of all,through the field research of QD supermarket,to understand the specific needs of QD supermarket management system.And through the analysis of the system user,the user of the QD supermarket management system is divided into four types of users,such as supermarket purchasing agent,inventory management,commodity sales staff and system administrators,and use case diagram analysis method to determine the specific functional requirements of different users in QD supermarket management system.Secondly,based on the functional non functional requirements analysis of QD supermarket,the design principle of QD supermarket management system and the overall structure of QD supermarket management system based on B/S three layer structure are determined,and the functional structure of QD supermarket management system and the data table structure are determined based on the analysis of system use case.Finally,using Java technology to carry out the QD supermarket management system of procurement management,inventory management,sales management,system management and other specific business functions of information technology.In order to reduce the cost of system development and operating costs,the system is implemented using Struts2+Spring+Hibernate open source free framework,the system database using MS SQL,the system server uses Linux open source operating system.It not only realizes the information of QD supermarket commodity management business,but also reduces the cost of system development and maintenance.Through the test results of QD supermarket management system,this paper shows that the QD supermarket management system designed by this paper can meet the daily management system of QD supermarket,and the performance of the system can also meet the needs of QD supermarket.
