Abstract
Disclosed is a database management method which generates an execution plan with respect to a factorized character string generated by factoring an execution value list of a query and stores the factorized character string and an execution plan identifier with respect to the factorized character string, matching each other. The database management method includes receiving, from a client, a factorized character string generated from a query; determining whether the factorized character string is stored in a memory; transmitting an execution plan identifier matching the factorized character string stored in the memory to the client when the factorized character string is stored in the memory, or generating and transmitting an execution plan identifier with respect to an execution plan of the factorized character string to the client when the factorized character string is not stored in the memory; receiving a query request consisting of the execution plan identifier and an execution value list included in the query from the client; and providing a query result obtained using the query request to the client.
