The Research And Achieve On Safety Storage Of Big Data Based On Distribute Database

With the development of information technology,the data size of information system is increasing continually.Big data has become the trend of the development of information technology,and the problems of big data safety storage have to be solved.Firstly,the requirements of big data are analyzed,and get the problems of big data storage and safety.With surveying the theory of big data,the paper gets the method to solve the problems.The paper gives the detailed introduction of key technology and innovation point which is used by the paper.And then,the paper designs the storage system,including framework,module,detail and ports.At last is the summary of the whole page and looking into the distance.The big data safety storage system which is designed by the paper not only satisfy the request of non-structuring big data,and also finish the safety modules of big data's storage by using distributed database to avoid that the safety modules become the bottleneck of the system.One of the innovation points of the paper is using non-metadata distributed file system to solve the problems on the management of the big data's metadata perfectly.And the other one is the related algorithm of virtual storage space mapping technology which is used by the paper.It realizes the unified management of different type storage by set up the storage pool.The paper accomplishes the development of big data safety storage system and related testing works,which is solved the problems preferably of big data safety storage used in secret information system.The storage system has been put into use in the production of virtual platform and meeting room system.
