Data Engineering for Beginners

Foreword

Over the past decade, I've worked across the spectrum of data-driven organizations—from nimble startups to global tech leaders. In that time, I've collaborated with data engineers, leaders, product managers, and countless others who rely on data to make decisions. Through both professional experience and online engagement with aspiring data engineers, I've noticed one recurring theme: confusion. Again and again, the same question surfaces: Who exactly is a data engineer, and what do they do?

I only wish this book had existed when I was starting out. It would've saved me countless hours lost in confusion and dead ends. Chisom Nwokwu delivers a rare combination: comprehensive coverage of data engineering, grounded in clarity, relevance, and real-world experience.

Each chapter invites readers deeper into the world of data engineering—from broad concepts to advanced techniques, all the way to practical steps for entering the field. With a thoughtful structure, well-chosen topics, and clear, accessible examples, this book makes the journey both exciting and informative. It's remarkable how much Chisom has packed into just a bit over 300 pages.

With data volumes growing exponentially, and businesses racing to turn information into a competitive edge—especially in the age of artificial intelligence—data engineering has become indispensable … and so has the knowledge captured in this book.

Whether you're just stepping into the world of data engineering or looking to sharpen ...
