Design And Implementation Of Online Learning System Based On Cloud Platform

The rapid development of information technology has promoted the reform andinnovation of colleges and universities.In recent years,many colleges have established information management systems,and the development of teaching work has been established.The main purpose of the construction of information systems is to facilitate teachers to carry out teaching,such as the launch of online learning systems,allows teachers to upload their teaching data to the system,students can use them online.Although this system can help students learn,it still has certain shortcomings,such as low use inefficiency of software and hardware,the difficulty of integrating application systems at all levels,the lack of original high-quality educational resources.A series of problems such as inability to guarantee the quality of online teaching and the incomplete sharing of teaching resources.In response to these problems,this thesis designs and develops an online learning system under the cloud platform to solve the lack of learning resources forstudents and to quickly find their favorite course resources among the many teaching resources.students and to quickly find their favorite course resources among the many teaching resources.This thesis conducted a field survey in a university,learned the actual needs of users for the cloud platform online learning system,and conducted an in-depth analysis of its development status,and Based on the analysis of the related technology and architecture of the system,the business functions of the system are constructed,and the online learning system based on the cloud platform is designed and implemented:1.This thesis selects the B/S development model after the analysis,use the three-level development model to build the software platform architecture,and use the Java programming language to develop each function.After the system design is completed,it will provide users with a network login interface.2.This paper adopts the method of UML modeling,and carries on the system analysis,system design,system realization and test work according to the method of object-oriented software engineering,make system each function is more abundant.3.The system integrates the design ideas of cloud computing and establishes a cloud platform model based on SOA and provides teaching services for student users with the help of online learning models of cloud services in parallel.Students can choose their favorite course resources,and design and implement teaching resource management function,online learning function,data query function,online examination function,course recommendation function,system management function and other modules.4.This thesis uses the black and white box test method to complete the system function and performance test,figures out the shortcomings through the test.
