Plan Calcul

An Execution Plan in a database is like a detailed map showing how the system retrieves data based on a query. It outlines the steps the database engine will take—such as which indexes to use or how to join tables—to efficiently deliver the answer. Analyzing this plan helps identify potential bottlenecks or inefficiencies, allowing you to optimize queries for better performance. Essentially, it shows the "recipe" the database will follow to get the data you asked for, making it easier to understand and improve the process.
