A database graphical comparison tool allows comparing database items that include multiple database statements and graphically displaying the comparison results in a ranked list of database statements. The graphical comparison tool includes a graphical user interface that allows a user to easily configure the tool for both manual and automatic (or scheduled) comparisons. In addition, the user may specify one or more actions that may be autonomically performed when the comparison of database items meets predefined criteria. Database items that may be compared using the database graphical comparison tool include optimizer monitors and plan cache snapshots.
