Research And Implementation Of Teaching Resouces Sharing System On Cloud Computing

Accompanying the development of the computer technology and network technology, The sharing of teaching resources is achieved by exploiting the network resources in most schools. The traditional network model for the sharing of teaching resources is likely to result in "information island", that result in links among the" islands "not smooth, it is also difficult to achieve the needs of users. So research approach of the teaching resource sharing system based on cloud computing is given in this paper. The design of this approach combines cloud computing and web development technology, makes full use of the characteristics of cloud computing, and reaches the purpose of the elimination of the "information island".The Google App Engine cloud platform is used in this system, which uses eclipse development tools to develop Java Web though Google Plug-in for Eclipse. The feature of the Google App Engine platform is showed absolutely in this system, which achieves the study of the teaching resource sharing finally.The concept of cloud computing and the model of cloud architecture are introduced in this thesis firstly, then the feature and function of each platform is given though a brief introduction of existing cloud platforms. Furthermore, the underlying technology and API of developing the Google App Engine is given in detail, then the design of the teaching resource sharing system is described, including business process design, functional modules design and data persistence design. In this case, we get a new solution to solve the difficult problem, which is the standard of J2EE and the map of traditional database storage model to the object data storage model can not be perfect to use in the Google App Engine environment. Finally, the given design combined with Google App Engine programming environment achieves teaching resource sharing system, which includes the business logic implementation, interface implementation and data persistence implementation.At last, we made a summary, point out the defect existing in the process of research, put forward its own proposal on the current problems, and propose a work plan in the next step.
