Exercises
This course provides a series of progressive and thoughtful exercises to reinforce course teaching.  Exercises range  from Try-This-Now quick work to longer, more thoughtful  approaches. Typically, course content is organised so that for every hour of the course, delegates have an exercise to do

Each Delegate Receives
1.    A workbook with a set of course foils and exercises
2.    A course disk with exercises and solutions where appropriate. Exercises include tables and data so that work can be repeated later.

.Please Note
This course does not include DBA responsible Server SQL tuning.  These techniques and skills are separately available.

Our Oracle SQL Performance and tuning training course is there to ensure that performance is considered when designing, coding and then later maintaining Oracle applications in production.

SQL Performance is always in an issue when designing, and later maintaining applications. Oracle systems today offer many different approaches to managing small and large tables effectively.  The performance options available have never been more varied and complex for designers and developers to choose from. 

This –very hands on- course provides a thorough grounding in the basic techniques required to code and evaluate different Oracle SQL approaches for solving challenging business problems.
