What you will learn:
In the Oracle Database: SQL Tuning for Developers course, you learn about Oracle SQL tuning and how to apply tuning
techniques to your SQL code. Learn the different ways in which data can be accessed efficiently.

Learn To:
 Use Oracle tools to identify inefficient SQL statements.
 Use Automatic SQL Tuning.
 Use Real Time SQL monitoring.
 Write more efficient SQL statements.
 Monitor and trace high load SQL statements.
 Manage optimizer statistics on database objects.
 Understand the optimizer process steps and operators.
 Interpret execution plans.
 Perform application tracing.
Benefits To You
Benefit from gaining a deeper understanding of Oracle SQL statement tuning and how write well-tuned SQL statements
appropriate for the Oracle database in this application development-centric course. You will learn how to decipher, decide
and then apply tuning to your SQL code. Various tuning techniques are demonstrated.
