Abstract:
Recent advances in mobile services have led to ever-increasing demands for high performance mobile database due to its data-centric characteristics. However, NAND flash memory, which is the main storage medium of mobile device has drawbacks in write operation because of its erase-before-write characteristics. In an attempt to overcome the drawbacks of the NAND flash memory, we propose a new mobile database management system (MDBMS), called P-SQLITE. It is enhanced with the find-grained data management techniques for using phage change random access memory (PRAM) as a caching layer between main memory and NAND flash memory. P-SQLITE continuously monitors the write patterns to identify hot chunk which is fine-grained file access unit and migrates the hot chunks from NAND flash memory to the PRAM. The experimental results show that the P-SQLITE improves the write performance by 47% than the previous MDBMS.
