Design And Implementation Of Vocational Education Teaching Resource Library Cloud Platform

In recent years,the education sector attaches great importance to the construction of educational teaching resources,teaching based on complementary advantages and characteristics,the development of a number of online education resource library and teaching material library,courseware,and online courses.Many education sector in the construction of teaching resources libraries have done a lot of exploration,and achieved some results,but still can not meet the requirements of educational informatization construction.Through research and analysis,the current vocational education teaching resource library resources mainly piled heavy application time low,slow content updates,resource classification confusion,evaluation and feedback mechanism is not perfect and so on.Based on these aspects,this study from the vocational education resource library construction standards begin,select internationally popular educational resource metadata standard IEEE LOM.Under this standard reference to and to regulate the Chinese online education technology standards as defined in the guidance system,and building a research-based teaching resource library system and vocational education cloud platform.The main work is as follows:(1)Based repository construction standards and related industry standards,in line with the construction of a model of vocational education resource library.This model meets educational resource metadata standard IEEE LOM.(2)System design based on SOA architecture design,the entire library system is divided into five levels,namely:the user interface layer,business logic,WEB service layer,a common component layer,data layer.The greatest benefit system layered architecture of the system is clear and reasonable business logic functionality of the system corresponds to a WEB service,fully embodies the characteristics of high cohesion and low coupling system,but also need to meet the application requirements of the Windows Azure cloud platform.(3)To achieve the end-user terminal equipment using cross-platform cross-repository systems,the study selected Microsoft's Windows Azure cloud computing platform as a service platform and database platform repository system.The use of technology to a variety of educational resources WCF service package to WebRole way to the Windows Azure cloud computing released on the platform and resources deployed to achieve different types of application platform for users to applications.Meanwhile,in order to fit the requirements of cross-language environment,the component layer,the use of technology to education resources Hprose service package to WorkerRole way to the Windows Azure cloud computing platform released and resource deployment to meet the application requirements of mobile terminals,improving a repository of application timeliness.This paper studied the system of vocational education teaching resource library resources compared with other database systems,more standardized classification of resources,resource updates easier and convenient,as the system is Windows Azure cloud computing platform-based design makes the application of resources with high timeliness and reliability.The system is designed for a variety of evaluation and feedback mechanisms resources,making the resource library system can achieve self-improvement resources,thus ensuring high utilization of resources and high access rate.
