               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.
