Data Engineer vs. Data Manager: A Detailed Comparison

Table of contents

In the world of Big Data, two roles that are often confused with each other are data engineer and data manager. While both roles deal with data, they have distinct differences in their responsibilities, required skills, and educational backgrounds. In this article, we will compare and contrast these two roles to help you understand which one is right for you.
