Syllabus

Module 1: Advanced SQL Techniques for Bulk Data Modifications

Learners will master enterprise-grade SQL patterns using CTEs, transaction control, and audit logging to safely execute bulk data modifications with complete traceability.

Module 2: Analyze Sampled Data Hashes to Identify Data Drift

Learners will implement cryptographic hash-based validation systems to detect data drift and verify transformations across large datasets without requiring full table comparisons.

Module 3: Create Idempotent Scripts for Versioned, Append-Only Data Updates

Learners will design and implement idempotent, append-only data update systems that preserve complete data lineage while ensuring script reliability and repeatability in automated pipelines.
