Before conducting demand analysis on this system, By conducting questionnaire surveys on users who meet the requirements of the system, analyzing their consumption patterns and usage habits, we can further develop the system. The survey results show that more and more people in today's society pay attention to the safety and health of food, and vegetables are also indispensable ingredients in life, so their safety is even more important. In the survey, most consumers are unable to taste the vegetables they want due to seasonal, regional and other limitations; they also buy stale vegetables because they are unclear about the source of the vegetables; and in the process of selling vegetables, merchants There are errors in the sales volume and purchase volume of vegetables due to manual operation; there are also some vegetables that are unsalable due to large inventory but insufficient publicity [10]. 3.1 User Requirements 3 System Requirements Analysis Acknowledgments 33 7 Conclusion 30 6.2.2 System backend administrator interface and function implementation 26 6.2.1 System front-end user interface and function implementation 23 6.2 Operating system interface and function implementation 23 6.1.2 Project technical architecture 23 6.1 Software development description 22 6 System implementation 22 5.2 System frontend user end Detailed design 20 5.1 Detailed design of the system backend administrator 15 5 Detailed design 15 4.3. 3 Database table design 12 4.3.2 Project E-R diagram design 12 4.3.1 Project entity design 10 4.3 Database design 10 4.2.2 System front-end user function module design 9 4.2.1 System background administrator function module design 8 4.2 Function modules Design 8 4.1 System structure design 7 4 Summary design 7
