摘要

Two of IT's most consistent mandates are lower costs and more speed. To meet this demand for cheap speed, standard disk-based database management systems need help. Increasingly, this help is coming in the form of memory-centric data management technology. Conventional DBMSs are designed to get data on and off of disks as safely, quickly and flexibly as possible. Much of their optimization is focused on one key bottleneck — the length of time it takes to find a random byte of data on disk, which is 1 million times as long as it might take to find the same byte in RAM.
