Coverage baselineSQL Server 2025 (17.x) baseline with current developer, security, HA, and AI/vector features

Course brief

From engine fundamentals to advanced production operations.

This syllabus deliberately separates conceptual foundations, hands-on SQL, engine internals, operational tooling, reliability, security, performance, and capstone work so future lesson generation can go deep without compressing advanced subjects into generic chapters.

By the end

You will be able to

Write production T-SQL and reason about storage, transactions, tempdb, indexes, and plans
Use Query Store, statistics, DMVs, wait analysis, and Extended Events for diagnosis
Design backup/PITR, Availability Groups, replication, and DR with explicit RPO/RTO
Apply SQL Server security, encryption, auditing, Agent automation, and integrity checks
Evaluate columnstore, In-Memory OLTP, vector/AI features, upgrades, and hybrid deployment choices
