Design And Implementation Of University Digital Resources Distributed Handling System Based On Hadoop

People cannot work without the computer and the Internet in the information age.The project development of the University digital resource management platform can integrate the digital resources of colleges so as to maximize the utilization of resources,effectively improve the teaching quality of teachers and the learning level of students,expand the interactive form between teachers and students,and improve the overall quality of the college.Original digital resources such as electronic documents,PPT,video,and so on,which cannot be well compatible with the new form of the Internet.For example,the PPT courseware and course video produced by university teachers,they will be uploaded immediately to the Internet if they are finished or photographed,which will directly cause difficulties in browsing online.Because the size of video or the format of courseware is not suitable for direct browsing in web pages,therefore it is meaningful to design and implement a system that can handle the digital resources of colleges and universities uniformly and provide online browsing interaction.If we use a single server to deal with resources and provide WEB service in the application of colleges,which will give pressure to the server,and it's time-consuming.In order to meet the low cost and high reliability of flexible access and service demand of sharing education resources,which can handle multiple resource files at a low cost based on the solution of the fusion of storage and resource-processing.In Hadoop,the MapReduce computing framework can be used to deal with digital resources,so as to process multiple file formats at the same time and improve the utilization of resources.Based on the application background of universities,this thesis investigates the current situation of university digital resources application,analyzes the requirements and designs the system in accordance to the requirements of digital resources application in universities,extracts the functional modules with strong generality,and uses the SpringMvc+MyBatis framework design to realize the business system of university digital resources'management and application.The purpose of the thesis is to research how to deal with common digital resources formats to make it convenient to browse directly in the Internet.And by using Hadoop distributed framework technology to design and implement the distributed processing of digital resources,so as to form a set of low-cost distributed system which can transform the teaching resources into a unified format.And the digital resources in and universities can be better spread and browsing through the Internet.
