The book famously outlines a four-step process for designing dimensional models:

: Determine exactly what one row in the fact table represents (e.g., one line item on a retail receipt).

The second edition of by Ralph Kimball and Margy Ross, published in 2002, is the industry-standard guide for dimensional modeling . It introduced fundamental techniques used to design high-performance, user-friendly data warehouses and business intelligence systems. Key Concepts & The Four-Step Design Process

: Choose the descriptive context ("who, what, where, when") for the measurements.

: Identify the operational activity to be modeled (e.g., retail sales, insurance claims).
