About this course

Slow-running database queries can bring applications to a halt, frustrating users and increasing infrastructure costs. Understanding how to optimize your database is one of the most valuable skills for any developer or database enthusiast. This text-based course guides you from the fundamental principles of database architecture to writing highly performant queries and robust database logic. You will transition from writing basic SQL to designing optimized database structures that handle data efficiently, understanding how the database engine processes queries under the hood to proactively prevent performance bottlenecks. What you'll learn: - Understand the core storage structures of SQL Server, including pages, extents, and heap tables. - Design and implement effective clustered and non-clustered indexes to accelerate search operations. - Analyze execution plans to pinpoint exact performance bottlenecks and costly table scans. - Write and optimize stored procedures, views, and user-defined functions for maintainable database logic. - Apply modern query tuning techniques, including avoiding common anti-patterns and utilizing modern execution features. - Troubleshoot locking, blocking, and concurrency issues to maintain high database availability. The course begins with a solid foundation in database storage and indexing theory before moving into practical query analysis, execution plans, and the creation of efficient database programmability objects. This progressive approach ensures you build a strong conceptual model before diving into hands-on optimization techniques. This course is designed for beginner to intermediate database developers, data analysts, and software engineers who have a basic understanding of SQL queries and want to build performant databases. No advanced administration experience is required. Start optimizing your database queries and build faster, more reliable applications today.
