Research And Development Of Signal Processing Course Group Management System Based On JavaWeb

In an era of increasing knowledge and information,traditional methods of curriculum management are no longer able to meet the needs of modern education.After investigating the situation of college teachers and students,it is found that the increase in the types of courses and the number of students has made it difficult for teachers' teaching management,and simple classroom teaching has not completely solved the problems encountered in students' learning.Therefore,the thesis proposes the research and development of the signal processing course group management system based on Java Web,and builds a course group management system that can provide multiple functions for teachers and students by means of information technology,which is convenient for teachers to manage courses,realize interaction with students and improve students' Learning effects.The main research work of the research and development of signal processing course group management system is as follows:(1)Based on the research of signal processing course group theory and Java Web technology,the system requirements analysis is carried out,and the UML model of course group management system is established by UML modeling technology.Based on the B/S architecture and MVC layered design idea,the system architecture design is completed,and the background business management is implemented by using the framework technology such as Spring Boot,so that the system has high cohesion and low coupling characteristics,keeping the system structure simple and clear.Through the top-down method,the logical structure of the system is analyzed,the entity relationship of the system is abstracted,and the system My SQL database is designed and optimized.This paper designs the system function,sets up the Vague evaluation model for the course evaluation function,divides the course evaluation level,makes the course evaluation standard and reasonable,which helps the system quality to be improved.(2)Based on the system design,user login,user management,role management,resource management,job management,course evaluation,online question answering,message notification,mail sending and other functions are implemented,and perform functional testing.The test results show that the management system realized by Java Webtechnology has stable performance and good portability.(3)Load Runner is used to complete the load stress test of the system,and perform performance test of system response speed,compatibility test of different operating systems and browsers,ensure that the system works properly on different platforms.The created signal processing course group management system provides functions such as course management,job management,resource management,course evaluation,online question answering,and message notification to realize information transfer and resource sharing.The construction of the signal processing course group management system makes the management of signals and systems,digital image processing and other courses more standardized,and the system can also be extended to other disciplines.The research content provides a good platform for education modernization and network teaching,and has certain application value and practical significance.There are 46 pictures,33 tables and 65 references.
