1. Introduction & Overview<\/strong><\/h1>\n\n\n\n

\u2753 What is a Data Catalog?<\/h3>\n\n\n\n

A Data Catalog<\/strong> is an organized inventory of data assets across your systems. It uses metadata to help data professionals discover, understand, trust, and govern<\/strong> data.<\/p>\n\n\n\n

\n

Think of it like a library catalog: you don\u2019t read all books, but you need to know where to find the right one, who wrote it, and whether it\u2019s relevant.<\/p>\n<\/blockquote>\n\n\n\n

\ud83d\udd70\ufe0f History or Background<\/h3>\n\n\n\n
    \n
  • Originated in data governance and business intelligence<\/strong> environments.<\/li>\n\n\n\n
  • Evolved with Big Data, AI, and cloud-native architectures<\/strong>.<\/li>\n\n\n\n
  • Modern catalogs integrate automated metadata discovery, lineage tracking,<\/strong> and security controls.<\/strong><\/li>\n<\/ul>\n\n\n\n

    \ud83d\ude80 Why is it Relevant in DevSecOps?<\/h3>\n\n\n\n

    In DevSecOps, security, development, and operations collaborate across data workflows<\/strong>. A data catalog helps by:<\/p>\n\n\n\n

      \n
    • Improving data discoverability and access control<\/strong><\/li>\n\n\n\n
    • Supporting secure automation pipelines<\/strong><\/li>\n\n\n\n
    • Enabling auditing, lineage, and governance<\/strong><\/li>\n\n\n\n
    • Aligning with privacy and compliance (e.g., GDPR, HIPAA)<\/strong><\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n
