Title Study of In-Memory Database technology and application
Abstract
Usually in a traditional disk resident database (DRDB) system, data is disk
resident, thus transaction processing often requires disk I/O operations.
Its architecture is optimized for reducing the amount of disk read and write
and increasing disk space usage. Therefore, DRDB support real-time
application poorly.
In a main memory database (MMDB) system, the primary copy lives permanently
in memory. Based on all data is kept in memory, MMDB has new architecture
design and new database management technology, as a result, it provide
higher access speed, faster response time and greater transaction
throughput than DRDB and is widely used in telecommunication, finance,
government area and so on.
This paper gives a brief introduction to In-Memory database technology,
makes a comparison to DRDB, and analyzes the similarities and differences
of the two different database products. Based on the non-exam system, we
simulate the score-management function, and test the performance of each
database systems. Finally we come to the conclusion that the In-Memory
database performance is about twice that of traditional disk database
performance under realistic conditions.
