Flash-Aware Page Management Policy of a Navigation-Specialized Mobile DBMS for an Incremental Map Update
Kyoung-Wook Min, Jeongdan Choi · IEICE Transactions on Information and Systems · 2013
The performance of a mobile database management system (DBMS) in which most queries are made up of random data accesses if the NAND flash memory is used as storage media of the DBMS is degraded. The reason for this is that the performance of NAND flash memory is good for writing sequentially but poor when writing randomly. Thus, a new storage structure and querying policies are needed in mobile DBMS when flash memory is used as the storage media. In this letter, we propose a new policy of database page management to enhance the frequent random update performance, and then evaluate the performance experimentally.
