The Design And Application Of University Teaching Resource Database System Based On Cloud Platform

With the development of the times,the data generated by people's daily work and life are growing exponentially.Meanwhile,the research and use of big data is in full swing.However,The increase of documents and a large number of teaching resources and resources equipment have been developed has put forward a new challenge and opportunity to the data storage,the data retrieval,the data analysis for reasons of requirements can not be met by normal resource library.Firstly,the dissertation analyzes and summarizes the current situation of cloud computing system and hadoop at home and abroad,and concentrate much attention on education;Secondly,In order to break the bottleneck of resource storage,and achieve one's goals for load balancing principle an hadoop server node,and reduce negative impact of small nodes for storing metadata in namenode,and perfect and high efficiency service to resource,and failure of the partial node,apart from causing even more hadoop server damage take a heavy toll on lossing resource and extracting resources from hadoop,and methods on the reform of hadoop was put forward for reasons of breaking through the limits of hadoop,such as the strategy of multi-Namenode,small file merging,resource multiple copy selection,and it show important source code on the important methods,which improve storage efficiency in aspect of resource,and build the resource library with the better method.In addition,follow requirement steps,the dissertation show all requirements of the resource database system from three aspects:functional requirements,performance requirements,running requirements;Secondly,The dissertation shows the overall education cloud platform and network topology for the resource database system on construction of resource library,which According to the rules,such as safety,widen and operate,the resource platform is set up;Thirdly,The dissertation proposes the measures and ideas on the construction and optimization of the resource database system;Fourly,The dissertation designs and realizes concretely important module'function for showing important interface and the source code.Finally,The dissertation establish a cloud platform of private teaching resource pool with Eucalyptus,hadoop,hbase and mysql,The administrator publish system as subfunction modules of this platform base on the Gridsphere portal system Web interface,The administrator publishs system as sub function modules of this platform base on the Gridsphere portal system Web interface,and catches out the system functional testing with test case in the environment for perfect running system;Secondly,in order to ensure the operation performance,some simulation users access the system simultaneously for uploading resource,downloading resource and searching resource,which confirms the rationality of design strategy,and greatly improves the user experience,and improves the utilization of teaching resources.
