Disclosed is a computer-readable medium including a computer program including encoded commands. The computer program is configured to cause one or more processors to perform operations for optimizing a database application when the computer program is executed by the one or more processors of a computer system and the operations include: operation for receiving a query including a bind parameter from an application source; operation for obtaining information related to the bind parameter included in the received query; and operation for rewriting the received query by reflecting the obtained information related to the bind parameter within the received query as hint information.

Optimization technique for database application

Provided is a computer program stored in a computer readable storage medium, which includes encoded commands, wherein when the computer program is executed by one or more processors of a computer system, the computer program allows the one or more processor to perform the following steps for generating a balanced parse tree having an optimized height, the steps including: receiving a token stream including at least one token&#x2014;the token stream meets an associate law&#x2014;; determining whether an n-ary parse tree is full&#x2014;the n-ary parse tree includes at least one node and the at least one node each includes n or less child nodes; a first node generating operation of generating a node while increasing a height of the parse tree based on the token stream when the n-ary parse tree is full; and a second node generating operation of generating the node while maintaining the height of the parse tree based on the token stream when the n-ary parse tree is not full.
