An arrow leads down from the SQL Profile icon to the lower box, which contains a box labeled "Optimizer (Normal Mode)." The arrow is labeled "Use." The Optimizer box points right toward a box labeled "Well-Tuned Plan." The arrow is labeled "Output." A page labeled "SQL" points right toward the Optimizer and is labeled "No application code change." To the left of the SQL page is a cluster of user icons labeled "Database Users."
