Design of Cloud Teaching Resource Sharing Platform Based on Hadoop

Efficient and rational use of teaching resources is the basis of teaching work in Colleges and universities. It is also the key factor to improve teaching quality. At present, there have been some achievements in the sharing of university teaching resources, but there are still many problems that need to be solved. Function design of platform of teaching resources sharing under the cloud computing environment, the construction of educational resources sharing platform of education, can share the low degree of the maximum resolution of resources and infrastructure construction is dispersed, the repeatability and excessive construction of resources, and the resource sharing platform of power, the integration of existing teaching resources, to improve the utilization of teaching resources, to maximize the value of the use of teaching resources. 1. Present Situation and Existing Problems of Teaching Resources Sharing in Colleges At present, with the development of distance education and online education, the teaching resources of colleges and universities are shared, to a certain degree, through the Internet, but the sharing degree of teaching resources is still poor. Colleges post some content in their own Web site, such as the school's recruitment information, academic conferences, literature, teaching resources and some other content. Because the universities’ digital resources have more entrances, the various information systems use heterogeneous platform, which caused the "resource island" phenomenon that some resource can not be used well. At the same time, most of colleges focus on the technology processing of the educational resources in detail, which makes the sharing of educational resources construction remain stagnant. The details are presented as follows: (1) There is a lack of valid argument and reasonable planning in digital resource construction. Most of schools resources construction is fragmented, redundant construction, randomness, resulting in waste of resources, the lack of unified planning and management at the macro level. (2) There is lack of unified resource construction standards and resource exchange platform. Most of colleges and universities establish the teaching resource base according to their own actual teaching needs, which makes the database interface standards between colleges and universities not to be unified, and it is difficult for each other to exchange data and interoperate with each other. As a result, the independent storage of teaching resources and the lack of exchange of educational information make it difficult to provide the guarantee for sharing resources. (3) The recall ratio of teaching resource search engine is not high enough, the search efficiency is low, and it is difficult to search the practical teaching resources quickly and accurately. 2. Function Design of Shared Teaching Resource Database Based on Cloud Computing The purpose of the construction of shared teaching resource database is to develop and integrate all kinds of high-quality teaching resources, avoid repeated construction and waste, and finally build a teaching resource sharing platform based on cloud computing. Therefore, the teaching resource sharing platform needs to break through the following points in functional design: (1) There are already a number of teaching resource systems in the university, the teaching resource sharing platform is able to exchange resources and share resources with other resources; 2nd International Conference on Computer Engineering, Information Science & Application Technology (ICCIA 2017) Copyright © 2017, the Authors.
