Design And Implementation Of Teaching Resource Database In Higher Vocational Colleges

In today's society,"Internet +" is widely applied in all walks of life,and education is no exception.At present,there are too many platforms for all kinds of online schools,which are mostly suitable for examination guidance and professional skills training.Of course,humanities education platform also exists,but for the construction and use of higher education resource platform,it is still not very mature.The major platforms that we are familiar with are Netease Cloud Classroom,Mu Course Network,etc.These platforms are rich in resources,but also very scattered.College students spend more time in consulting information on the platform.Especially the students in higher vocational colleges have greatly affected their enthusiasm.How to enable students to quickly and effectively find online teaching resources requires such a platform to collect these teaching resources from the Internet and store them in the network teaching resources data warehouse of Higher Vocational colleges.The search engine of teaching resources in higher vocational colleges can help students retrieve resources on the network,and at the same time,it can realize the function of sharing and retrieving resources in the platform of teaching resources management.Through the related technology of distributed crawler and the related design of teaching resources platform construction,this paper realizes the search engine system of teaching resources in Higher Vocational colleges,which integrates the search,sharing,downloading and storage of teaching resources.In the research,HBase database is used as the storage database of distributed crawler data acquisition system.Static task partition is used to schedule tasks.Hash-based rearrangement algorithm is used to schedule tasks.SSH framework is used in grid resource platform.The established resource search engine system has the functions of resource sharing,resource retrieval,resource management,resource download and so on.Using distributed crawler technology,the speed of searching is accelerated by using control nodes to direct the work of crawler nodes.The information of teaching resources on the Internet is from crawling,drying,extracting to obtaining effective information,and then preserving.At the same time,relevant resource platforms are established to enable students to quickly search for network teaching resources.The results of this study can help vocational students quickly find the resources they need and reduce the time of data search.At the same time,make full use of computer classification,retrieval,storage and other information technology to simplify and facilitate resource search.At present,the system has been tested and has some effect.
