improves space efficiency : smaller size of database file. improves time efficiency : faster processing speed. improves parallelism : higher performance in multi-thread environment. improves usability : simplified API. improves robustness : database file is not corrupted even under catastrophic situation. supports 64-bit architecture : enormous memory space and database file are available.
