Data Modeling – The Unsung Hero of Data Engineering: An Introduction to Data Modeling (Part 1)

This article delves into the world of data modeling, its crucial importance within the broader context of data engineering, and its fascinating history. Data modeling is a structured representation of an organization's data that helps understand relationships, constraints, and patterns within the data. It plays an indispensable role in creating efficient systems such as data warehouses, lakes, or analytics solutions. The article explores different levels of data modeling, from conceptual to physical, and discusses how data modeling is essential for successful data projects. Furthermore, it highlights key concepts of data modeling, including normalization and metrics, and provides a brief history of data modeling's evolution over the years.
