In this book Ralph Kimball, a true visionary in the area of data warehousing, explains how the extract, transform, and load (ETL) – by far the most difficult and time-consuming part in building a data warehouse – needs to be properly planned, designed and build in order to deliver data in a presentation-ready format. Starting from the ETL fundamentals, you will learn how to correctly build both relational and dimensional data structures.
