She will lead you through 3 days of learning on dimensional modeling from the basics to the most advanced practices. The dimensions must be defined within the grain from the second step of the 4-step process. In normalized models, data is divided into many discrete entities and even a simple business process might result in dozens of tables joined together in a complex way. Building on the bus architecture foundation established in Chapter 5, it's time to delve into the basics of dimensional modeling.This chapter begins with an overview of fact and dimension tables, along with the fundamental activities of drilling down, drilling across, and handling time in the data warehouse. Basic Fact Table Techniques 41. Margy Ross is president of the Kimball Group. Margy Ross is President of the Kimball Group. Chapter 6 Dimensional Modeling Fundamentals. [3][4] To build the schema, the following design model is used: The process of dimensional modeling builds on a 4-step design method that helps to ensure the usability of the dimensional model and the use of the data warehouse. After defining the dimensions, the next step in the process is to make keys for the fact table.
