Research And Implementation Of Online Education Platform System Based On Cloud Computing

Online education, also known as E-learning, is a network as a medium of teaching mode, through which, teachers and students can do teaching activities even if they are separated from thousands of miles; In addition, students can also download the network courseware resources at any time, which breaks the limit of space and time. For those who work busy and don't have fixed learning time, online education is the most appropriate way.Aiming at the problems of traditional education such as the limited scope of audience, low utilization rate of resources, inconvenient data sharing, high cost of development and operation and maintenance, this paper puts forward a scheme of building an online learning platform based on cloud computing. The online education system based on SaaS(software and service) mode encapsulates the common function modules of the traditional teacher teaching platform into service, and adopts the architecture model of service-oriented system development to construct the online learning platform,which changes the traditional educational software into a service. This paper studies the service and characteristics of cloud computing, and builds an online education platform based on cloud computing combined with the demand of Tsinghua Tongfang Joyle Education Technology (Beijing) Co., Ltd. Specific work:(1) According to the real teaching process, the paper analyzes the needs of the online education system from the system users and the main use cases, and puts forward the system design goal and the system structure including the logic structure, technology structure and function structure of the online education system based on cloud computing.(2) According to the demand analysis and the system design goals,the main function modules of the system are designed in detail, including user management, teaching resource management, online learning tasks and interactive discussion four modules. For SaaS mode, the system needs to provide services for different tenants, the multi-tenant data isolation technology is proposed, and the system data module is designed on this basis.(3) Complete the main function of online education system modules including user management, learning resource management, online learning tasks and interactive discussion by using MyEclipse development tools, Java web development technology.(4) Testing the main function of the system by using the black box test method, and display the test page.The use of service-oriented model in online education platform compared with the traditional online learning platform, hardware and software resource utilization more efficient, more rational allocation of resources for schools and users,the development and maintenance costs lower cost, which gives an advantage in improving teaching efficiency and has a very good value in practice.
