The Design And Implementation Of Vocational Colleges Curriculrm Resource Sharing System On Cloud Platform

With the rapid development of information technology,the amount of data produced every day is increasing rapidly.The increment of teaching resources and curriculum resources,such as teaching video,teaching audio,teaching document,and so on,is increasing rapidly.To deal with these data,the storage capacity and calculation ability have exceeded the single service.The ability of a device to store and handle.Through the research and study,we can make use of cloud computing,large data and other technologies to build a resource sharing platform for the growing curriculum resources,data storage and data processing services of high vocational school,and use distributed computing and distributed search engine technology to solve the problems of data processing and data search,and through the large data platform Collecting and processing user access to teaching resources,log data,and according to the statistical status of teaching resources recommended services and other functions.Based on the cloud platform,the vocational college curriculum resource sharing system is based on the learning of the Hadoop system,building a distributed storage platform,using the MapReduce distributed computing framework and ElasticSearch to share,recommend and search the course resource data,and mainly do four aspects.(1)use the virtual software to integrate all kinds of computer hardware resources into the integrated pool deployment cloud computing platform,and use the Hadoop distributed file system HDFS cluster to store the curriculum resources of higher vocational colleges,and solve the unstructured data such as teaching video files,teaching audio files,teaching documents and so on.The problem of volume storage space.(2)general flume collects user access to log records,and then uses distributed computing framework MapReduce to analyze log records,and provides users with recommended curriculum resources services based on collaborative filtering algorithm.(3)build a Hadoop system on a private cloud platform through a distributed cluster,and deploy a distributed search engine ElasticSearch to provide users with a course resource search service to solve the problem of users' access to curriculum resources and retrieval of curriculum resources.(4)through Web Service,data visualization and other technologies to provide Web friendly access interface,to realize the distribution of curriculum resources in Higher Vocational Colleges on the cloud platform,to provide users with user registration,user login,uploading resources,downloading resources,sharing resources,recommending resources,searching course teaching resources and so on.
