Data Architect vs. Data Modeller: A Comprehensive Comparison

Table of contents

In the world of Data management, two roles that are often confused are Data Architect and Data Modeller. While both roles are essential in designing data solutions, they have distinct responsibilities and skill sets. In this article, we will compare and contrast the roles of Data Architect and Data Modeller.

Definitions

A Data Architect is responsible for designing, creating, and maintaining the overall Architecture of an organization's data ecosystem. This includes designing the data storage, data integration, and data management systems.
