Oracle Discoverer 4.1 for Power Users

Request more details:

Experienced Oracle Discoverer users are interested in knowing how the advanced features of the Oracle SQL language can be incorporated into Discoverer queries. Within this course users will learn how to enhance their queries through the use of correlated subqueries, functions, processing of hierarchies and other advanced SQL techniques. When these advanced techniques are combined with the ease-of-use features of Oracle Discoverer then users are fully empowered to extract crucial information from their databases and data warehouses.
Participants would need to have a good working knowledge of Oracle 9i Discoverer or have attended an Oracle 9i Discoverer Administration course.
