Overview of this book

The volume of data continues to grow as warehouses are populated with increasingly atomic data and updated with greater frequency. Dimensional modeling has become the most widely accepted approach for presenting information in data warehouse and business intelligence (DW/BI) systems. The goal of this book is to provide a one-stop shop for dimensional modeling techniques. The book is authored by Ralph Kimball and Margy Ross, known worldwide as educators, consultants, and influential thought leaders in data warehousing and business intelligence. The book begins with a primer on data warehousing, business intelligence, and dimensional modeling, and you’ll explore more than 75-dimensional modeling techniques and patterns. Then you’ll understand dimension tables in-depth to get a good grip on retailing and moved towards the topics of inventory. Moving ahead, you’ll learn how to use this book for procurement, order management, accounting, customer relationship management, and many more business sectors. By the end of this book, you’ll be able to gather all the essential knowledge, practices, and patterns for designing dimensional models.

In the Figure 17-1 Kimball Lifecycle diagram, the middle track following the business requirements definition focuses on data. We turn your attention in that direction throughout the next several sections.

Dimensional Modeling

Given this book’s focus for the first 16 chapters, we won’t spend any time discussing dimensional modeling techniques here. The next chapter provides detailed recommendations about the participants, process, and deliverables surrounding our iterative workshop approach for designing dimensional models in collaboration with business users. It’s required reading for anyone involved in the modeling activity.

Physical Design

The dimensional models developed and documented via a preliminary source-to-target mapping need to be translated into a physical database. With dimensional modeling, the logical and physical designs bear a close resemblance; you don’t want the database administrator to convert your lovely dimensional...
