MAIN-MEMORY DATABASE SYSTEMS:
DESIGN AND PERFORMANCE TRADEOFFS
The demand for fast response time and the availability of
larger and inexpensive memories are motivating database sys-
tem designers to consider Main-Memory Database Systems
(MMDBS) as a viable alternative to Disk Database Systems
(DBS), which assume that databases reside on disk during
transaction processing. One of the first operational MMDBS
prototypes is implemented in the OBE (Office-By-Example)
system, an integrated office-environment system developed at
IBM Watson Research Center. The core of OBE is a complete
relational MMDBS, which exploits the memory residence
assumption in its approach to database physical design,
query processing algorithms, and query optimization.
In this talk, we will describe a benchmark of the OBE MMDBS.
Then, using OBE as a case study, we will propose new perfor-
mance metrics and analyze design tradeoffs for future main
memory database systems.
