DB2 PARALLEL EDITION

The rate of increase in database size and response-time requirements h as outpaced advancements in processor and mass storage technology. One way to satisfy the increasing demand for processing power and input/o utput bandwidth in database applications is to have a number of proces sors, loosely or tightly coupled, serving database requests concurrent ly. Technologies developed during the last decade have made commercial parallel database systems a reality, and these systems have made an i nroad into the stronghold of traditionally mainframe-based large datab ase applications. This paper describes the DB2(R) Parallel Edition pro duct that evolved from a prototype developed at IBM Research in Hawtho rne, New York, and now is being jointly developed with the IBM Toronto laboratory.
