Research on Structured Storage and Index of Data Flow in Disaster Tolerance System
Based on the problem that the storage of data flow lacks structure and the data retrieval speed is slow in some disaster tolerance systems, a structured data storage and high efficient data retrieval model is proposed in this paper. In this model, the circular queue structure is used in the dynamic shared memory buffer pool, which has improved the storage efficiency of real-time data flow; the circular queue data storage structure and an improved B+ tree index structure are used in the hard disk, which has solved the problem that how to store new data when the storage space is full, and improved the data retrieval efficiency in some degree. Test results show that this model has better data storage capacity and faster data retrieval speed.
