Data Catalog
A Data Catalog is like a company's digital library card system for all its data. It helps organizations keep track of what data they have, where it's stored, and who can use it. Think of it as a shopping catalog but for data - it shows what's available, describes what it means, and helps people find the information they need quickly. Companies use Data Catalogs to make sure everyone knows what data exists and can use it properly for business decisions. It's similar to how a store inventory system tracks products, but instead of tracking physical items, it tracks information and data sets.
