In this application development-centric course, delegates learn about Oracle SQL statement tuning and how to write well-tuned SQL statements appropriate for the Oracle database. Delegates learn to interpret execution plans and the different ways in which data can be accessed.

Delegates are shown how to decipher, decide and then apply tuning to their SQL code. Various tuning techniques are demonstrated. For example, taking advantage of bind variables, trace files, and using the different types of indexes are utilized.
