Query Analysis

Glossary Page

Query analysis is a database process that involves using SQL to examine and optimize queries for better performance. It plays a crucial role in query processing by enhancing overall performance, resulting in faster database operations. To achieve this, a query optimizer evaluates individual query statements and generates both local and remote access plans based on the resource costs associated with each plan. The database then selects the plan that is expected to process the query with the lowest resource cost.
