enhances SQL performance, saving time and effort that would otherwise be spent on manual optimization. In pre-production, it scans database objects and source code to find and fix problematic SQL statements by providing optimized alternatives, allowing for immediate improvements in SQL performance. In production, the tool goes further by generating automated indexes and conducting impact analysis to predict how changes in index creation, database settings, upgrades, and object growth will affect performance.
SQL Optimizer for Oracle enhances this with query optimization features that boost performance and make database administrators more productive. The Oracle Query Optimizer is crucial in processing every SQL statement and determining the best execution plan by analyzing the query structure, statistical data on the underlying objects, and various optimization and execution features.
