Transaction Management for Flash-based Database Systems*

[Abstract]

Owing to their superiority in access latency and energy consumption, flash memory drives have recently become a competitive alternative to magnetic hard disks as secondary storage. Consequently, flash-based database systems have been receiving increasing attention from the research community in the past few years. In this project, we plan to investigate a number of optimization techniques for transaction management in flash-based database systems by exploiting the characteristics of flash memory drives (such as out-of-place updates and page reprogramming).
