Abstract
A novel and unique method, apparatus and programmed storage medium for approximating large data distributions of a database in order to allow a user to accurately analyze the entire data distribution using a limited amount of memory space in a reasonable amount of time. The approximation is based on partitioning the data domain into a number of regions, approximating each region using any well-known technique, and composing the errors of approximation to optimize suitable criteria for approximating the entire data distribution.
