1. A computer-implemented method of analyzing performance data, the method comprising: executing, on a processor, an analysis tool, wherein the analysis tool is configured for: receiving event records of performance data for query statements executed by a relational database management system; condensing the performance data in each respective event record into a summary, wherein the summary for a respective event record includes at least one characteristic of a query statement obtained during execution of that query statement; identifying at least one executed query statement based on the at least one characteristic, wherein the executed query statement is issued by at least one application program; generating, from the condensed event records related to the identified query statement, a performance summary for the executed query statement; and generating a performance summary for the at least one application program from at least the performance summary for the executed query statement.
