Fundamentals of Metadata

📚 What is Metadata?

Think of metadata as data about data. Just like a library card tells you about a book (title, author, subject), metadata tells you about a data asset—its structure, origin, meaning, and usage. 

 There are four main types:

 🔹 Technical Metadata – Table names, data types, relationships, lineage

 🔹 Business Metadata – Business definitions, ownership, rules

 🔹 Operational Metadata – Job runs, access logs, data usage

 🔹 Administrative Metadata – File sizes, formats, access rights

 🛠 Why Metadata Management Matters

 Metadata management is the process of organizing and governing metadata across your enterprise. It's more than documentation—it's the backbone of a well-functioning data ecosystem.

 Here’s how it powers data governance:

 ✅ Data Discovery – Easily find and understand data

 ✅ Improved Data Quality – Context helps define and enforce quality rules

 ✅ Data Lineage – Track where data came from and how it’s transformed

 ✅ Compliance – Satisfy GDPR, HIPAA, CCPA requirements

 ✅ Security – Manage sensitive data with appropriate access controls

 ✅ Integration – Bridge systems with consistent definitions and standards
