Design And Implementation Of Remote Class Service System With The Characteristics Of Cloud Services

With the rapid development of society and the acceleration of knowledge explosion progress, the numbers of education training institutions in China are on the increase. In order to further expand the market and provide education training for students with different demands, the methods of education training have turned to remote education based on the Internet from the original face to face type of teaching. The purpose of the study of remote class service system with the characteristics of cloud services is to solve this practical need.This paper mainly puts emphasis on design and implementation of remote class service system with the characteristics of cloud services. First, project development background of the system and introduction of RESTful Web Service, Restlet and oAuth is summarized. Then, this paper begins with four kinds of system users, which are education institution administrators, remote class system administrators, remote class teachers and students using remote class, and designs system service process, underlying database, internal interfaces of each module of the system and external interfaces of the system. After that, it discusses the process of how to use REST and Restlet technology to implement functions such as merchant management, resource management, base services, order services, authentication and so on. It also contains the detailed design and implementation of the important parts of the system, including how to authenticate Web Services used in this research and how to optimize the process mode of REST style in session management and role management. In addition, the part of software testing tests all functions from two aspects, unit testing and integration testing. The system is tried in real machine and the test results are analyzed and summarized. At the end of this paper, the design and implementation of remote class service system with the characteristics of cloud services is summarized, and suggestions of improvement of the system are pointed out.
