Abstract: Character strings can be sorted according to the attributes of characters therein in an order suited to the significance of the characters. Dividing means divides character strings to be sorted in a database according to the attributes and creates management tables associated with the respective attributes. Attribute-dependent sorting order determining means determines sorting orders suited to the respective attributes of the management tables and sets values of sorting order indexes associated with respective character strings in the management tables. Sorting means compares the character strings of each attribute with each other, and determines a sorting order of character strings with an identical attribute in accordance with the values of the sorting order indexes, to carry out sorting.
