Method, apparatus, and computer program stored in computer readable medium for conducting arithmetic operation efficiently in database management server

A non-transitory computer-readable medium including a computer program which is configured to cause one or more processors to perform a process when the computer program is executed by the one or more processors of a database computer system, wherein the process comprises:

• receiving a structure body creation request for performing a predetermined accumulative arithmetic operation on a plurality of numerical values stored in memory of the database computer system by a network;
• creating a structure body including array elements in response to the structure body creation request by the network, wherein the number of the created structure bodies is plural;
• receiving an arithmetic operation processing request for processing of the predetermined arithmetic operation with respect to the plurality of numerical values stored in the memory of the database computer system by the network;
• creating structure body number data for each of the plurality of the numerical values stored in the memory of the database computer system by applying each of the plurality of the numerical values stored in the memory of the database computer system to the created structure body, the created structure body including one or more array elements and at least some of the numerical values being allocated to the one or more array elements to create the structure body number data by the one or more processors of the database computer system;
• and
• performing the predetermined arithmetic operation based on the structure body number data for each of the plurality of the numerical values to acquire an arithmetic operation result data, the predetermined arithmetic operation including an addition arithmetic operation of the numerical values stored in the memory of the database computer system,
• wherein the size of each of the array elements of the plurality of structure bodies are different from each other
• wherein each of the one or more array elements represents a predetermined multiplier of a specific number, and
• wherein the operation of acquiring the first arithmetic operation result data includes performing the predetermined arithmetic operation between values possessed by the array element in which the predetermined multiplier is identical.

A database server having memory and a processor for performing a predetermined accumulative arithmetic operation, the server comprising:

• a structure body creator configured to receive a structure body creation request for performing a predetermined accumulative arithmetic operation on a plurality of numerical values stored in memory of the database server by a network and create a structure body including array elements in response to the structure body creation request by the network, wherein the number of the created structure bodies is plural;
• a structure body number data creator configured to receive an arithmetic operation processing request for the predetermined arithmetic operation for a plurality of numerical values stored in the memory of the database server by the network and create structure body number data for each of the plurality of the numerical values stored in the memory of the database server by the network by applying each of the plurality of the numerical values stored in the memory of the database server by the network to the created structure body, the created structure body including one or more array elements and at least some of the numerical values being allocated to the one or more array elements to create the structure body number data by the one or more processors of the database server;
• and
• an arithmetic operation processor configured to perform the predetermined arithmetic operation based on the structure body number data for each of the plurality of the numerical values to acquire an arithmetic operation result data,
• wherein the size of each of the array elements of the plurality of structure bodies are different from each other
• wherein each of the one or more array elements represents a predetermined multiplier of a specific number, and
• wherein the operation of acquiring the first arithmetic operation result data includes performing the predetermined arithmetic operation between values possessed by the array element in which the predetermined multiplier is identical.
