During this four-day instructor-led course you will learn how to design, create and deploy all three layers of the Oracle BI repository. Expert instructors will teach you how to use the Oracle BI Administration Tool to administer and manage the repository and you will build a dimensional model and related analyses to verify your work. You will also browse related query logs to verify queries generated by OBIEE.
