Databases Systems with Large Main Memories By Leonard D Shapiro Presented By Aditya Tayade Yongjoo Park Motivation make the most of what you have Joins tend to be one of the most costly operations. SHAPIRO North Dakota State University Systems We study algorithms for computing the equijoin of two relations in B system with a standard architecture hut with large amounts of main memory Our algorithms are especially efficient when the main memory R. If hybrid bash, combines the two, doing all partitioning on the first pass over each relation and using whatever memory is left to build a hash table. It performs well over a wide range of memory Dilation: Join Broken Segments Erosion and Dilation: Eliminating Irrelevant Details Closing Hit or Miss Operator Region Filling Connected Components Thinning Thickening: Thinning the complement Gray S Yin Yang. , Dimitris Papadias, Stavros Papadopoulos.
