1. Project Introduction
The widespread application of the Internet has brought great convenience to life. Therefore, the learning record and reminder application management is combined with the current network, and Java technology is used to build the learning record and reminder application app to realize the informatization of the learning record and reminder application. This can play a significant role in further improving the development of learning record and reminder application management and enriching learning record and reminder application management experience.
The study record and reminder application app can be widely and comprehensively promoted through the Internet, so that as many users as possible can understand and be familiar with the convenience and efficiency of the study record and reminder application app. It not only provides services to the masses, but also promotes itself, allowing More people understand themselves. For learning record and reminder applications, if you have your own app, you can get better management through the system and improve your image at the same time.
The current status and trends of this app design, from the design of requirements, structure, database, etc. to the implementation of the app, are front-end and back-end implementation respectively. The content of the paper shows the development process from the aspects of system design, description, implementation, analysis, and testing. This app chooses a feasible development plan based on the actual situation, and uses the Java programming language and mysql database to realize all the functions of the app. Next, the system is tested to test whether there are loopholes in the system and test user permissions to improve the app. Finally, the app Completion meets relevant standards.
2. System functions
This learning record and reminder application management system mainly includes three functional modules, namely the student function module and the teacher function module and the administrator function module.
(1) Administrator module: Home page, personal center, student management, teacher management, learning material management, type management, learning record management, suggestion information management, homework information management, student homework management, correction information management, online consultation management, reply Information management, forum management, system management and other functions.
(2) Student APP interface: home page, study materials, homework information, forum, mine, etc. On the My page, you can manage personal center, study records, suggestion information, student homework, online consultation, my collection management, and I want to post , My Post and other functions to operate.
(3) Teacher module: Home page, personal center, learning material management, learning record management, suggestion information management, homework information management, student homework management, correction information management, online consultation management, reply information management and other functions.

3.1APP home page
Log in. The user enters the app and enters his or her account number and password to log in to the system.
To register as a student, enter the registration page and fill in the student ID, password, confirmation password, name, gender, email, mobile phone number and other information to register.
After students log in to the system, they can perform detailed operations on the homepage, study materials, homework information, forums, mine, etc.
For learning materials, you can view the material name, material cover, type, video, key points and difficulties, job number, teacher name, release date, material introduction, material content and other information on the learning material page.

Students can operate detailed information such as personal center, study records, suggestion information, student assignments, online consultation, my collection management, I want to post, and my posts on my page.
3.2Backend management
For background login, administrators and teachers can log in to the system by entering their username and password, selecting a role and clicking Login.
After the administrator logs in to the system, he can view the home page, personal center, student management, teacher management, learning material management, type management, learning record management, suggestion information management, homework information management, student homework management, correction information management, online consultation management, Reply information management, forum management, system management and other functions, and you can also perform corresponding operations on each function one by one
