The Research of Key Technology in Flash-Based DBMS

As the capacity of flash memory increases and price drops, flash memory will compete more successfully with disk drives. It is thus not inconceivable to consider running a full database system on the flash-only computing platforms or running an embedded database system on the lightweight computing devices. In this paper, the characteristics of flash memory and the key points of designing a flash-based DBMS were analyzed. And a new design called In Block Logging (IBL) for flash memory based database servers was presented.This new design overcomes the limitations of flash memory such as high erase latency, and exploits unique features of flash memory to achieve the best attainable performance for flash-based database servers.
