Scenario: A developer is tasked with optimizing the performance of a database application. How can Visual Explain aid in this optimization process?

Visual Explain in DB2 helps developers optimize database application performance by identifying opportunities for index usage optimization. By analyzing the query execution plan generated by Visual Explain, developers can determine whether the queries are utilizing indexes efficiently. Efficient index usage can significantly enhance query performance by reducing the need for full table scans and minimizing disk I/O operations. Therefore, leveraging Visual Explain enables developers to make informed decisions about index creation, modification, or deletion to enhance the overall performance of the database application.
