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.

Agile Considerations

Currently, there’s significant interest within the DW/BI industry on agile development practices. At the risk of oversimplification, agile methodologies focus on manageably sized increments of work that can be completed within reasonable timeframes measured in weeks, rather than tackling a much larger scoped (and hence riskier) project with deliverables promised in months or years. Sounds good, doesn’t it?

Many of the core tenets of agile methodologies align with Kimball best practices, including

  • Focus on delivering business value. This has been the Kimball mantra for decades.
  • Value collaboration between the development team and business stakeholders. Like the agile camp, we strongly encourage a close partnership with the business.
  • Stress ongoing face-to-face communication, feedback, and prioritization with the business stakeholders.
  • Adapt quickly to inevitably evolving requirements.
  • Tackle development in an iterative, incremental manner.
