What can be analyzed to understand contributions of individual query executions?

To understand the contributions of individual query executions, analyzing database statements is particularly insightful. Database statements encompass the actual SQL commands issued to the database, allowing for a direct examination of what is being executed and how it is influencing performance metrics. By evaluating these statements, one can identify specific queries that may be causing bottlenecks, consuming excessive resources, or underperforming, thus enabling targeted optimization efforts.

Execution plans can provide context about how a database executes these statements, offering insights into performance, but they do not reveal the actual queries executed in a straightforward manner. Database structure gives an overview of how data is organized but does not directly inform about the efficiency or performance of individual query executions. System configurations affect overall system performance but are too broad and do not focus solely on the contributions of specific queries.

In summary, database statements offer the most relevant analysis for understanding the contributions of individual query executions, providing direct visibility into how each statement impacts resource usage and overall database performance.
