Learning Objectives

Online analytical processing, (OLAP), as succinctly different to OLTP   (transactional processes) enables fast multi-dimensional analytical   (MDA) queries. This Oracle OLAP Essentials workshop will explore OLAP data models to enable attendees to support and address the needs of a broad range of business intelligence project requirements.

Hands on labs are structured throughout courses and will include exercises to enable delegates to design and build OLAP cubes to serve as a summary management resource for existing SQL table queries, through to adding rich analytic content to attendees data models. Further hands on labs will provide delegates with skills to develop their own sophisticated reports of OLAP data by using simple SQL queries, to execute OLAP queries in SQL Developer or Oracle tools, and progress to apply cube security, access control, exploring best practice including performance.

Pre-Requisites

  • SQL for Oracle
  • A base understanding of OLAP and BI concepts is helpful, athough not essential
