The memory-based column repository has become an attractive architecture for big database storage because of its compression performance, and the cheap flash drive has become a popular storage for high-performance servers because of its outstanding I/O performance, and non-volatile, power-economic nature. First, we introduce a popular raw-oriented storage model and a new column-oriented model. Second, we propose a dual-index model using flash memory to improve the performance of the high-speed column-oriented database system. Our index management scheme achieves superior search performance by index segmentation and compact indexing. In terms of the search performance, our scheme outperforms traditional index management schemes.
