System introduction:
With the rapid development of information Internet shopping, most companies are creating their own management systems. This article introduces the entire process of development of the edible mushroom stick traceability system. By analyzing the enterprise’s needs for the edible mushroom stick traceability system, a computer-managed edible mushroom stick traceability system program was created. The article introduces the system analysis part of the edible mushroom stick traceability system, including feasibility analysis, etc. The system design part mainly introduces the system function design and database design.
Administrator of this edible mushroom stick traceability system, ordinary administrator, ordinary user. Administrator functions include personal center, ordinary user management, ordinary administrator management, basic information management, growth information management, bacterial room information management, etc. Common administrator functions include personal center, common user management, basic information management, growth information management, bacterial room information management, etc. Common user functions include personal center, basic information management, growth information management, etc. Therefore it has certain practicality.
This site is a B/S mode system. The backend uses the SSM framework as the development technology. The frontend uses VUE development technology and MYSQL database design and development to fully ensure the stability of the system. The system has the characteristics of clear interface, simple operation and complete functions, making the management of edible mushroom stick traceability system systematic and standardized.
The system is a website system based on B/S architecture. The designed functional structure diagram is shown below:
When the program is handed over to the user for use, the operation flow chart of the program needs to be provided, so that the user can easily understand the specific working steps of the program. Nowadays, the operation process of the program has a general standard, that is, first submit the login data through the login page, After the program is verified correctly, the user can operate the corresponding function on the program function operation area page.
