Parallel Query Processing in Object-Oriented Database Systems
Clement H. C. Leung, David Taniar · Victoria University Research Repository (Victoria University) · 1994
Parallelization techniques are used to improve peiformance of Object-Oriented Database (OODB) query processing.Several parallelization techniques, especially those relating to parallelizing path expressions and explicit joins, are examined.Data distribution is a major concern in parallelization, since performance improvement depends on a good data distribution method.Two alternatives are described to overcome load imbalance: re-distribution and replication.General analytic models for a distributed memory parallel architecture are presented, and peiformance evaluation is carried out.
