Comparison of Partitioning Techniques Evaluate how well partitioning techniques support the following types of data access: 1.Scanning the entire relation. 2.Locating a tuple associatively-point queries. E.g,KA=25. 3.Locating all tuples such that the value of a given attribute lies within a specified range-range queries. E.g.,10≤rA<25.
