Research And Implementation Of University Teaching Resource Sharing System Based On Hadoop

In recent years,the Ministry of education,the Ministry of finance,the national development and Reform Commission jointly issued a plan named “promote the world's first-class universities and the implementation of the first class disciplines”,that marking the start of the double class construction started,and Chinese college education is being developed rapidly and vigorously.The application of science and technology in higher education industry is reflected in the aspects of collocating and sharing the teaching resource allocation and sharing.Although the nation attaches great importance to the development of the education,but there still has many problems.There is a great difference between the developed region and undeveloped region in distribution of teaching resources in colleges.Teaching resources in undeveloped region falls behind in developed region,and it has poor equipment,and technological application level draggles with the developed region.Although the college has rich teaching resources,and its teaching ability even more perfect,it still exists the problem of the "information island",the use of resources is closed,resulting in redundant construction of resources,rate of resources' utilization is reduced greatly,impede communication in a large amount of teaching resources,restricts the progress of science and technology education in colleges.In view of the above factors,this paper designs and researchs a sharing platform which has open,unified,and suitable for all areas of the college teaching resources.This platform in order to solve the existing resources' problems like uneven distribution,repeated construction,and low utilization rate.And then shorten the cycle of sharing educational resource,reduce the investment in education equipment.Finally,to promote the sharing and integration of educational resources,the informatization and networked of the education level will be orderly and healthy development.The work done in this paper is as follows:1.The factors restricting the development of China's higher education informatization are discussed,indicate that the necessity of developing teaching resources sharing system.In the process of construction,how to ensure the storage of enormous teaching resources information has become an problem that should be solved eagerly.Using Hadoop to architecture system,not only it is easy access to Hadoop,but also put the complexity of the massive data processing process simplified greatly.2.This paper analysis the advantage of Hadoop to sharing resource in the process of system's building.First of all,it explores the two important components of Hadoop: HDFS and MapReduce.Then,it expounds the integration of Hadoop technology and college teaching resources sharing system.It constructs an open source with parallel computing and distributed architecture based on the traditional B/S model,using HDFS to store massive education resources,and the parallel programming model called MapReduce to provide parallel calculate the search function.The SSH framework is used as the system framework that consists of Struts,Spring and Hibernate.Three of these frameworks combine with each other,and to complete the structure stable and reusable.3.According to the concrete operation mode of the system,the function module and the basic work flow of the system are designed.The design framework and conceptual structure are show with a clear and explicit E-R diagram.Create a database table that contains all of the data required by the system,there is consisted of the user information table,the administrator information table,the resource information table and the bulletin information table.According to the general principles of system development,this paper designs and implements the teaching resource sharing system of the University,which contains the functions of login,resource management,resource retrieval,online resource learning and so on.
