The Java language, Spring framework, SpringMVC framework, MyBatis framework, SpringBoot framework and MySQL used in this system development.
1. System Analysis
(1) Teacher management needs. The school wants to easily check the information of the designated teacher. The school conducts a basic information management for the teacher, and the school can easily query the basic information of the teacher. Teachers can be assigned class management, and teachers' teaching tasks can be arranged.
(2) Student management needs, the school conducts a basic information management of students, and can assign students to new classes. Assign the students to the corresponding classes, and enter the basic information of the students.
(3) Curriculum management, the classroom in the university is a shared place, and the class schedule cannot be posted in the classroom for students to check like high school. Each student can query the corresponding class schedule through their own class, which is convenient for the normal implementation of students' class order.
(4) Grades management, final exams are held every semester, and students care about their grades. At the same time, some students did not want to let other students know because they failed the exam. To protect their privacy, they cannot be notified in the form of files in the class group. Students are required to log in to the student management system of Deyang Academy of Agricultural Sciences to inquire about their personal grades, and cannot inquire about the grades of other students. Teachers can query all student grades.
(5) Login requirements. Since the data managed by the school is relatively private, the security of the data needs to be protected. Teachers and students must log in to access and use. The administrator needs to provide teachers and students with accounts.
Technical feasibility is a very important consideration when designing and implementing a student information management system. This section will analyze the feasibility of Java and its related technologies.
Java is a cross-platform programming language, which has the characteristics of high efficiency, safety, reliability, and portability. It has become one of the preferred languages for developing Web applications. In the Java ecosystem, there are many mature frameworks and tools to choose from, such as Spring, SpringMVC, MyBatis, and SpringBoot. These frameworks can improve development efficiency, reduce development costs, improve code quality and maintainability, etc. Therefore, it is very feasible to choose Java as a development language and use these frameworks and tools when developing a student information management system.
The Spring Framework is a lightweight framework that helps developers quickly build enterprise-level applications. It provides many functions, such as IoC, AOP, transaction management, Web development, etc., so that developers can focus more on the realization of business logic. SpringMVC is a sub-project of the Spring framework. It is a web framework based on the MVC pattern, which can help developers quickly build web applications. MyBatis is a lightweight ORM framework that can be used to map Java objects to relational databases. SpringBoot is a rapid development framework based on the Spring framework, which can help developers quickly build web applications.
MySQL is a popular open source relational database, which has the advantages of high efficiency, reliability, and stable performance. It is a very suitable database management system for student information management system.
Therefore, in terms of technical feasibility analysis, Java and its related technologies are very feasible choices, which can improve development efficiency, reduce development costs, improve code quality and maintainability, and MySQL is also a very suitable for student information management system. database management system.
2. System design
The purpose of the system outline design is to determine the software system design scheme and formulate the schedule on the basis of the feasibility analysis. The main content is as follows.
First, the determination of the software architecture. At present, there are more and more mobile terminal users in the market, and relatively fewer and fewer PC terminal users. The B/S architecture can be accessed using the built-in browser whether it is a PC or a mobile terminal, and is compatible with the PC and mobile terminals. One is that the B/S architecture does not require the development of the client, and the system development cost is greatly reduced. Choose the B/S architecture to get the best of both worlds.
Second, the choice of technology. The system software development back-end chooses Java development, and uses the SpringBoot framework for fast and efficient development. The advantage of SpirngBoot is that it encapsulates the SSM framework internally. Further simplifies the use of the SSM framework, greatly saving unnecessary XML file configuration. The front-end page display uses html for data display. Use CSS cascading style sheets to beautify the page. Since front-end and back-end are relatively popular technologies today, only one back-end is needed, and the front-end can choose html pages or applets, Android applications, and so on. The database uses Mysql database, which is free and compact. In terms of economic feasibility analysis, it is feasible. Since Java is a cross-platform high-level programming language, it can be deployed on Linux systems. Not limited to the platform, compile once and run everywhere.
Third, design the system software structure. According to the results of the requirements analysis and the construction of the use case model, the overall structure of the system is divided into 4 modules, as shown in the figure
