Research on Agent-based Distributed Query Optimization
Jiang Jian-wen · Microelectronics & Computer · 2002
Internet is a large,autonom ou s system in which coexistence of heterogeneous hardware modules and the various kinds of available parallelisms make new challenges todistributed query optimiza tion.This paper combines the distributed artificial intelligence with distribut ed database system and presents an agent-based query optimization model.In thi s model,we adopt deliberative agents based on BDI.Each database agent possesse s the capacity of learning and reasoning based on its belief and goal,and multi agents interact with each other to support the dynamic query optimization and p lan execution.Thus,the performance of the whole system can be improved efficie ntly.
