Abstract

Disclosed is a computer program stored in a computer readable storage medium according to an exemplary embodiment of the present disclosure. The computer program executes operations for enhancing search performance of data when the computer program is executed by one or more processors and the operations may include: setting a traverse time stamp of an index search for searching a target index key; searching the index tree along a link connected from a root node of the index tree to a leaf node; writing in a time stamp table at least one index time stamp of the root node and the leaf node passed in the index search; determining whether a path of the index search needs to be changed; and determining a start node of re-search at least partially based on the time stamp table.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0014308 filed with the Korean Intellectual Property Office on February 07, 2019, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to database management methods, and more particularly to methods for searching indexes of databases.
