ESTIMATION OF QUERY COST IN OBJECT ORIENTED DATABASE SYSTEMS

Wu Shengli (Institute of Software, Chinese Academy of Sciences, Beijing 100080) Wang Nengbin (Department of Computer Science, Southeast University, Nanjing 210096)  
Good query optimizers are all based on cost, so the estimation of query cost is an indispensable work in query optimization. Based on association operation and considering the factor of index and object clustering, an estimation method for query cost in object oriented databases is presented.
