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

What is GDPR?<\/h3>\n\n\n\n
\"\"<\/figure>\n\n\n\n

The General Data Protection Regulation (GDPR)<\/strong> is a data privacy law enacted by the European Union (EU) in May 2018<\/strong>. It governs how organizations collect, store, process, and transfer personal data of individuals within the EU, regardless of where the company itself is based.<\/p>\n\n\n\n

In the DataOps context<\/strong>, GDPR ensures that data pipelines, automation workflows, and analytics processes comply with privacy and security regulations<\/strong>.<\/p>\n\n\n\n

History or Background<\/h3>\n\n\n\n
    \n
  • 1995:<\/strong> The EU introduced the Data Protection Directive (95\/46\/EC)<\/strong>.<\/li>\n\n\n\n
  • 2016:<\/strong> GDPR was adopted, replacing the older directive.<\/li>\n\n\n\n
  • 2018:<\/strong> GDPR became enforceable with strict penalties (up to \u20ac20 million or 4% of annual revenue<\/strong>).<\/li>\n\n\n\n
  • Today:<\/strong> GDPR is the global benchmark for data privacy laws, influencing similar regulations like CCPA (California), LGPD (Brazil), PDPA (Singapore)<\/strong>.<\/li>\n<\/ul>\n\n\n\n

    Why is it Relevant in DataOps?<\/h3>\n\n\n\n

    DataOps focuses on agile, automated, and secure data management<\/strong>. GDPR is crucial because:<\/p>\n\n\n\n

      \n
    • Data pipelines handle personal data (PII)<\/strong>.<\/li>\n\n\n\n
    • Companies must ensure privacy-by-design<\/strong>.<\/li>\n\n\n\n
    • CI\/CD workflows must comply with data retention and consent rules<\/strong>.<\/li>\n\n\n\n
    • Cloud environments require data residency and security alignment<\/strong>.<\/li>\n<\/ul>\n\n\n\n

      Without GDPR compliance, DataOps initiatives risk legal, financial, and reputational damage<\/strong>.<\/p>\n\n\n\n

      \n\n\n\n

      2. Core Concepts & Terminology<\/h2>\n\n\n\n

      How GDPR Fits into the DataOps Lifecycle<\/h3>\n\n\n\n
        \n
      • Data Collection:<\/strong> Ensure user consent and lawful basis.<\/li>\n\n\n\n
      • Data Ingestion:<\/strong> Encrypt and validate sensitive data.<\/li>\n\n\n\n
      • Data Storage:<\/strong> Follow retention policies, restrict access.<\/li>\n\n\n\n
      • Data Processing:<\/strong> Anonymize\/mask personal data.<\/li>\n\n\n\n
