Title: Character string data retrieving system
Inventor: MUGITANI TAKAO
IPC: G06F17/30
Filed: 1988-07-22
Abstract: PURPOSE:To reduce the number of times of the comparison of character string data, and to shorten a retrieving time by storing a random number value together with the character string data, generating the random number value at the time of retrieve, and first comparing them. CONSTITUTION:When a user inputs a character string data storing request through an input means 1, a character string data memory means 2 designates the inputted character string data, accesses a random number generating means 3, and generates the random number value. The means 2 stores them into a data base 5 as the second character data and the random number value. When the user inputs the character string data retrieving request, in the same way as the storing request, the first character string data and the random number value are generated by a character string data retrieving means 4 and the means 3. Next the first and second random number values are compared, only at the time of correspondence, by comparing the character string data character by character, the number of times of the comparison necessary for the retrieve can be reduced, and the time can be shortened.
