Design And Implementation Of Online Learning System Based On Cloud Platform

With the development of cloud computing technology and big data technology,the implementation of online learning has more conditions.It has the advantages of convenient resource updating,convenient real-time communication,high stability and flexibility.All of these lay a good foundation for the development of online learning platform.The aim of this system is to provide convenient learning channels for different types of learners by combining advanced digital resources,and to facilitate communication among employees and evaluation of learning effects,so as to ensure that learning effects can be improved.This paper first analyzes the background and significance of enterprise online learning system based on cloud computing,and then analyzes the system related development technology and architecture mode according to its development status.Then according to the requirements of the system to build a functional module,design and implementation of cloud-based enterprise online learning system,can provide different types of course learners with personalized communication and learning services.The research content of this paper can be divided into the following aspects:(1)Based on the implementation background and development status of cloud computing enterprise online learning system,this paper analyzes and summarizes the AJAX asynchronous refresh technology,key technologies of Google cloud computing,Google App Engine and other key technologies developed in this system.(2)Demand analysis is conducted on the relevant processes of the online learning system of cloud computing enterprises to clarify the functions that the system needs to achieve;The business process of the system is described by means of sequence diagram.(3)Based on B/S(browser/server pattern)architecture,this paper realizes the effective separation of system business and display through MVC design pattern,making the system structure more clear.The system implements several modules related to learning resources,testing,user management and interaction.(4)The cloud computing enterprise online learning system is tested in detail,including the system function and performance test,and further ensure the practicability and reliability of the system.
