What is Data Catalog?
Data Catalog is An inventory of data assets in your organization with metadata, descriptions, and usage information.
Definition
A data catalog is like a library card system for your company's data. It indexes tables, columns, dashboards, and reports across your data infrastructure. Each asset gets metadata: what it contains, who owns it, how fresh it is, and who's using it. The goal is making data discoverable so people don't recreate what already exists.
Why It Matters
Data teams waste time recreating analyses that already exist because they can't find them. Business users don't know what data is available. A data catalog solves the discovery problem. It's essential for organizations with multiple data teams or complex warehouse structures.
Example
A new analyst needs customer churn data. Instead of asking around, they search the data catalog, find an existing churn table, see its documentation and freshness, and start their analysis immediately.
