1 Understand Basics

To master data warehousing, you must first solidify your understanding of its foundational concepts. Data warehousing involves collecting data from various sources, transforming it into a format suitable for analysis, and storing it in a central repository. This repository, the warehouse, supports business intelligence activities by providing a unified source of truth. Familiarize yourself with the key components such as Extract, Transform, Load (ETL) processes, data models, and the role of Online Analytical Processing (OLAP) systems in facilitating complex queries.

A great place to start if you want to understand the idea of data warehousing in general is to read the books by the authors of the data warehouse modeling concept, namely: Inmon, Kimball and Linstedt. In these books we have not only descriptions of modeling, but also how to implement ETL processes for each sub-approach, so after reading them we already have enough knowledge to move on to practice. This knowledge is useful not only for data warehousing specialists, but also for data lake and data lakehouse specialists.
