Computer evaluation system based on SSM framework
Summary
As information technology becomes more and more in-depth and widely used in management, ordinary users begin to pay attention to their own information display platform, and the computer evaluation system based on the SSM framework is technically mature. This article introduces the entire development process of a computer assessment system based on the SSM framework. By analyzing users' needs for a computer assessment system based on the SSM framework, a computer management solution for the computer assessment system based on the SSM framework was created. The article introduces the system analysis part of the computer evaluation system based on the SSM framework, including feasibility analysis, etc. The system design part mainly introduces the system function design and database design.
This computer evaluation system based on the SSM framework has two roles: administrator and user. Administrator functions include personal center, user management, computer type management, computer category management, computer brand management, computer information management, computer evaluation management, forum mutual assistance, system management, etc. User functions include personal center, computer brand management, computer information management, computer evaluation management, my collection management, forum mutual assistance, system management, etc. Therefore it has certain practicality.
This site is a B/S mode system, using Java's SSM framework as 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 computer assessment system management work based on the SSM framework systematic and standardized.

Abstract
With the more and more in-depth and extensive application of information technology in management, as a general user, they have begun to pay attention to their own information display platform, and the realization of a computer evaluation system based on the SSM framework is technically mature. This article introduces the whole development process of computer evaluation system based on SSM framework. By analyzing the user's needs for a computerized evaluation system based on the SSM framework, a program for computer management of the computerized evaluation system based on the SSM framework was created. The article introduces the system analysis part of the computer evaluation system based on the SSM framework, including feasibility analysis, etc. The system design part mainly introduces the system function design and database design.
The computer evaluation system based on the SSM framework has two roles: administrator and user. Administrator functions include personal center, user management, computer type management, computer classification management, computer brand management, computer information management, computer evaluation management, forum mutual assistance, system management, etc. User functions include personal center, computer brand management, computer information management, computer evaluation management, my collection management, forum mutual assistance, system management, etc. So it has a certain practicability.
This site is a B/S model system, using Java's SSM framework as the development technology, and MYSQL database design and development, which fully guarantees the stability of the system. The system has the characteristics of clear interface, simple operation and complete functions, which makes the management of the computer evaluation system based on the SSM framework systematized and standardized.
