1. Introduction

Understand the foundation: what a data catalog is, why it matters, and the business value it delivers.

1.1 What is a Data Catalog?

A data catalog is an organized inventory of all the information assets inside an organization — tables, views, dashboards, KPIs, reports, and datasets. It acts as a single source of truth that answers the most common data questions: What data do we have? What does this field mean? Who owns it? Where does it come from?

1.2 Why Organizations Need a Data Catalog

As organizations grow, data becomes scattered across dozens of databases, dashboards, and tools. Without a catalog, teams face recurring problems:

• Data silos: each team keeps its own private copy of information.
• Duplicated effort: analysts spend 60–80% of their time finding and cleaning data instead of analyzing it.
• Broken trust: inconsistent definitions generate conflicting reports.
• Compliance risk: no visibility over sensitive data or who accesses it.
• Slow onboarding: new team members need weeks to understand the data landscape.
