Design And Implementation Of Online Shopping System Based On ThinkPHP Framework

Online shopping system is a system that businesses use the Internet to sell goods to customers,and sell goods to all over the world through the Internet and logistics network.Through the establishment of online shopping system,the offline commodity resources are transformed into online digital resources,the information of commodity sales is released through the Internet,the scope of commodity sales is expanded,and then the commodities are delivered to customers through the offline logistics netwo rk.Using online shopping system to integrate online and offline resources plays an important role in improving sales quota and reducing sales cost.In this paper,the design and implementation of online shopping system as a research entry point,from the perspective of buyers and businesses,using computer technology to design an online shopping system to simulate commodity sales.In order to understand the research situation of the subject,the research materials related to e-commerce and online shopping at home and abroad are consulted,and the research status,basic theory and research direction of the subject are analyzed in depth.In order to further understand the software development technology,this paper analyzes the current mainstream design technology and implementation technology of software,analyzes its characteristics,advantages and disadvantages,and selects the development technology suitable for online shopping system.In the analysis and design stage of online shopping system,the softwar e and hardware requirements of online shopping system are analyzed first to determine the structure diagram of online shopping system.In order to analyze the function of online shopping system,the object and data flow of the system are analyzed.From the perspective of buyers,administrators and tourists,the UML use case diagram is used to analyze the functional requirements of the system,and the overall business function diagram of online shopping system is sorted out.In order to better design the system function,the system function is divided into two major functional modules: foreground and background,and the specific function is designed in detail with sequence diagram and flow chart.When designing,we should fully consider the needs of various users and pay attention to the security and user experience of the system.When designing the system database,follow the database design process,design the E-R conceptual model of the database according to the data flow diagram of the system,and then determine the structure of the system data table.In the implementation and test stage of online shopping system,it is necessary to build and configure the development environment of the system and create the database of the system.In order to improve the efficiency of development,in the implementation of system development,phpstorm tool is used to build the Think PHP framework and plan the directory structure of system development.The function of the foreground mainly considers page layout,information input and display,user search and other contents,while the function of the background mainly considers the update operation of the database such as commodity information and order information.The deployment of the system and the development of the test plan are completed before the test,and the test of the system is completed according to the test plan.The last part of this paper is to summarize and prospect,review the process of system design and development,find out the existing problems,and think about the measures and development direction of system improvement.
