High-Performance SQL for JPA and ORM Developers

Many developers rely on ORMs to handle database logic, but inefficient queries can lead to significant performance bottlenecks as applications scale. Understanding the relationship between your code and the underlying database is essential for building responsive, scalable software. This course provides a clear path to mastering SQL performance tuning specifically for those working within abstraction layers. You will transform your approach to data access by learning how to bridge the gap between object-oriented code and relational database efficiency. The curriculum focuses on identifying hidden overhead and implementing modern best practices for data retrieval and persistence. What you'll learn: - Understand the fundamental mechanics of SQL execution and how ORMs translate code into database queries - Master indexing strategies to speed up data retrieval and improve overall application responsiveness - Apply batching techniques and connection pool tuning to optimize high-volume data operations - Identify and resolve common performance pitfalls like the N+1 query problem and inefficient joins - Practice writing optimized queries that balance developer productivity with database efficiency - Implement modern observability patterns to monitor and profile SQL execution in real-time The course begins with essential database terminology and foundational concepts before moving into practical optimization techniques for real-world application development. This text-based program is designed for beginners and intermediate developers who want to ensure their data-driven applications perform at their peak.
