Optimization design of electronic commerce system based on the basic principles of software engineering

Based on the basic principles of software engineering, this paper optimizes the design of e-commerce system from the aspects of demand analysis, system design, coding, implementation, testing and maintenance. Specifically, this paper adopts the object-oriented software development method, using the UML modeling tools to model the system, adopted the MVC architecture mode to realize the stratification of the system, using the front-end technology such as HTML, CSS, JavaScript to realize the user interface design of the system, combined with the back-end technology such as Java, JSP, the Servlet system. Through the system test and the use of code quality control tools, the system is accepted, and the maintenance of the system is planned and designed. Finally, this paper realizes an easy-to-use, stable, safe and efficient e-commerce system.
