Abstract

A storage system which efficiently achieves access with different Keys is provided. A data storage unitof each of data nodesstores a part assigned to the data nodeof each of main and sub tables. The main and sub tables respectively use first and second data elements as Key. When a value of one data element of the first and second data elements is inputted, the data acquisition unitobtains a data set including the inputted value from the assigned part of a table that uses the one data element as Key, using the inputted value as Key. Alternatively, the data acquisition unitobtains a data set including the inputted value from the assigned part of a table that uses the other data element as Key, using a value of the other data element corresponding to the inputted value as Key.
