Non-structured data access for cloud storage Xie into Chen Xiangdong unstructured data is exploding, and existing storage technology needs to be improved in the aspects of I/O throughput capability, scalability and manageability. Based on the theory of cloud storage and reliability, the storage system establishes a distributed storage model of unstructured data and designs a reliability function. The Distributed relational database management system (RDBMS) is used as the storage base, and the unstructured data is stored directly in the data table, which realizes the separation of unstructured data and metadata.
