This document provides an overview of dimensional modeling and loading dimensions and cubes using Oracle Warehouse Builder. It discusses key concepts like dimensional modeling, star schemas, slowly changing dimensions, and orphan management. It also describes how to define dimensional objects like dimensions and cubes in OWB and how the dimension and cube operators help to efficiently load data into those objects while handling issues like SCDs and orphans. Overall, it outlines how OWB supports dimensional modeling and ETL to help implement production data warehouse processes.
