Summary

Every year, a large number of candidates are not very clear about which colleges and majors their college entrance examination scores are suitable for when filling out their college entrance examination applications. College entrance examination candidates face the problem of not being admitted by colleges, being transferred to other majors, or even repeating their studies. If candidates can easily query relevant information such as college admission, college majors, and college enrollment, it can reduce a large number of candidates' mistakes in filling out college entrance examination applications. In response to these problems, this study proposes the design and implementation of a college entrance examination service system based on the SSM framework.
During the research process, this study first completed the system requirements analysis and clarified the system's functional and performance requirements; then, based on the results of the requirements analysis, the overall architecture and functional modules of the system were designed; based on the system design, this study carried out system coding implementation, including the development of the front-end interface and the processing of the back-end business logic; finally, the system was rigorously tested and optimized to ensure the stability and efficiency of the system.
The college entrance examination service system implemented in this study has been verified by actual application and has shown good performance and stability. The system not only improves the efficiency and accuracy of college entrance examination candidates' filling in, but also provides more convenient and efficient services for candidates and managers to help college entrance examination candidates choose the colleges and majors that suit them and are their favorites.

Overall functional requirements analysis

The overall process of the system refers to the operation process of the entire college entrance examination management system, including the interactive process of user login, information query, information management and other functions. The overall function of the system is described below.
First, the user enters the user name and password through the system login page to log in. The system will verify the information entered by the user. If the verification is successful, the user has successfully logged into the system; otherwise, the system will prompt the user to re-enter the information.
After successful login, the system will determine the user's permissions based on their identity. Administrators can manage university information, enrollment brochures, professional newsletters and admission information, including adding, deleting and modifying; ordinary users can only query information, including university information query, enrollment brochure query, professional newsletter query and admission information query.
In the information query function, users can query according to different conditions, such as university name, enrollment major, admission score, etc. The system will retrieve the corresponding information from the database according to the user's query conditions and display the query results to the user.
In the information management function, administrators can manage university information, enrollment brochures, professional newsletters and admission information. Administrators can add new information, including basic information of universities, detailed contents of enrollment brochures, relevant information of professional newsletters and specific circumstances of admission information. Administrators can also modify and delete existing information.
During the operation of the system, the system will record the user's operation log, including login records, query records, information management records, etc. Administrators can view the operation log to understand the system usage and user operation behavior.
The overall business process diagram of the system is shown in Figure 3-1.
The overall process has been described. The system's operating process is that the user logs in to the system, determines permissions based on identity, and performs information query or information management. Through this process, the function of the college entrance examination management system is realized.

System non-functional requirements analysis

System non-functional requirements analysis refers to the analysis and definition of system performance, availability, security, reliability and other requirements. This chapter will analyze the non-functional requirements of the college entrance examination service system, including performance requirements, availability requirements, security requirements and reliability requirements.
1. Performance requirements: The system should have good performance and be able to respond quickly to user requests. This includes the following aspects:
(1) Response time: The system’s response time to user requests should be controlled within 2 seconds to ensure smooth and efficient user operations.
(2) Concurrency: The system should have good concurrent processing capabilities and be able to handle requests from multiple users at the same time to avoid system crashes or slow responses.
(3) Data processing capability: The system should be able to efficiently process large amounts of data and ensure the accuracy and completeness of the data.
2. Usability requirements: the system should have good user experience and ease of use, and be able to meet user needs. Specifically, it includes the following aspects:
(1) User-friendly interface: The system's user interface should be concise and clear, in line with user habits and convenient for users to operate.
(2) Easy to understand and simple to operate: The system's operating procedures should be simple and clear, allowing users to quickly get started without the need for complex training.
(3) Error handling and prompts: The system should have a good error handling mechanism that can promptly detect and prompt users of erroneous operations and provide corresponding solutions.
3. Security requirements: The system should have good security to protect the user's personal information and the system's data security. Specifically, it includes the following aspects:
(1) Identity authentication: The system should have a user identity authentication mechanism to ensure that only authenticated users can access the system.
(2) Data encryption: The system should encrypt and store sensitive data to prevent data leakage.
(3) Authority control: The system should have authority management functions, and different users should have different operating authorities to ensure the security and integrity of data.
4. Reliability requirements: The system should have good stability and reliability to ensure long-term operation without failure. Specifically, it includes the following aspects:
(1) Fault recovery: The system should have an automatic fault recovery mechanism that can automatically handle faults and ensure system reliability.
(2) Data backup: The system should have a data backup function and regularly back up system data to prevent data loss or damage.
(3) Logging: The system should have a complete logging function that can record the system's operating status and user operations to facilitate troubleshooting and system optimization.
By analyzing and defining the non-functional requirements of the system, we can ensure that the system can meet user needs in terms of performance, availability, security and reliability, and improve the overall quality of the system and user experience.

Overall functional module structure design

The overall functional module structure design of the system refers to the overall division and organization of each functional module in the system to achieve the purpose of clear system functional modules, reasonable structure, easy maintenance and expansion. When designing the overall functional module structure of the system, it is necessary to consider the main functions and requirements of the system, and make reasonable division and organization according to the relevance and coupling between functions. For the college entrance examination service system based on the SSM framework, its overall functional modules can be divided into the following modules:
1. User management module: includes functions such as user registration, login, and personal information management, and is used to manage various types of users in the system, such as administrators and students.
2. College information management module: used to manage the basic information of each college in the system, including the name, address, contact information, etc. of the college, as well as the enrollment and admission information of the college.
3. Admissions Brochure Management Module: used to manage the admissions brochures of various colleges and universities, including enrollment plans, registration time, admission standards, etc., to facilitate students to query and understand enrollment information.
4. Professional newsletter management module: used to manage professional newsletters of various universities, including professional names, academic system, training objectives, etc., to facilitate students to query and understand professional information.
5. Admission information management module: used to manage the admission information of various colleges and universities, including the admission results and admission notices of candidates, so as to facilitate students to inquire and understand the admission status.
The detailed system functional structure is shown in Figure 4-3.

The above modules can be organized and managed through Spring MVC in the SSM framework, and the modules can interact and communicate with each other through appropriate interfaces and data transmission methods. At the same time, the modules can be divided and combined as needed to meet the specific needs of the system.
