Quest SQL Optimizer for Oracle validates database code to ensure the best-possible performance by helping you proactively identify potential issues and automate the SQL optimization process. 

Quest SQL Optimizer for Oracle scans and analyzes SQL, then identifies potential performance issues directly from running SQL statements, PL/SQL or other source code. It explores every possible way of improving SQL performance and either proves that you already have the best-performing SQL or provides you with the best-performing SQL alternative. 

With Quest SQL Optimizer for Oracle, you also have a complete index optimization and plan change analysis solution -- from index recommendations for multiple SQL statements to simulated index impact analysis, through comparison of multiple SQL execution plans.
