Abstract
The sorting device comprises a distribution monitoring and cell splitting section which analyzes a distribution of a sort target data group consisting sort target data and obtains an appearance frequency of the sort target data for each sorting segment based on a sorting key. A sorting segment setting section sets sorting segments for dividing the sort target data group into segments based on the analysis by the distribution monitoring and cell splitting section. A sorting mode selection section selects a quick sorting mode if the appearance frequency is equal to or higher than a preset threshold and selects a radic sorting mode if the appearance frequency is lower than the threshold, for each sorting segment. A sorting execution section executes sorting for each sorting segment based on the selected sorting mode.
