SQL for Business Intelligence Reporting and Analysis


After a short introduction on Data Warehousing (DW) and Business Intelligence (BI) topics, this course examines in depth the possibilities offered by SQL. More specifically, statistical, analytical and OLAP functions will be discussed and explained. The most important ones are then individually discussed and demonstrated; realistic hands-on practical sessions give attendees the chance to grasp quickly the applicability of these SQL functions and options.

The SQL syntax covered in this course is platform independent. When relevant, platform specific exceptions will be pointed-out with respect to Oracle, Db2, and SQL Server.

This course is also available for exclusive, one-company presentations live over the Internet, via the Virtual Classroom Environment service.
