About the Course
Modern organizations frequently struggle with escalating cloud database costs and application latency caused by unoptimized data layers. This course addresses these challenges by providing a practitioner-led deep dive into the internals of relational database management systems (RDBMS). You will move from writing simple queries to architecting high-performance data solutions that adhere to ACID compliance while maintaining the flexibility required for modern software development. The curriculum focuses on five core domain capabilities: query cost analysis, physical storage optimization, advanced analytical patterning, concurrency management, and distributed scaling strategies. We utilize industry-standard tools such as PostgreSQL and Microsoft SQL Server to demonstrate universal optimization principles applicable across any relational environment.
During this five-day intensive, you will learn to diagnose performance issues using diagnostic views and system catalogs. You will practice hands-on query rewriting to eliminate N+1 problems and optimize join orders in complex multi-table environments. We distinguish between conceptual coverage of distributed systems and hands-on implementation of local indexing and schema refactoring. This course teaches database performance tuning through rigorous execution plan analysis so you can deliver measurable improvements in query response times. You will walk away with a toolkit of optimization scripts, indexing checklists, and architectural frameworks designed for immediate application in production environments where data integrity and speed are non-negotiable constraints.
Target Audience
This program is built for technical professionals who already possess a strong foundation in SQL and are responsible for the performance, scalability, and reliability of data-driven systems.
This course is designed for:
- Senior Backend Engineers managing high-traffic application data layers
- Database Administrators (DBAs) responsible for enterprise RDBMS performance
- Data Engineers building scalable ETL pipelines and data warehouses
- Full-Stack Developers optimizing database interactions in web applications
- Data Architects designing resilient and performant schema structures
- Performance Engineers focused on identifying and resolving system bottlenecks
- Cloud Solutions Architects overseeing managed database service implementations
- Senior Data Analysts requiring advanced analytical SQL for complex reporting
- Site Reliability Engineers (SREs) monitoring database health and latency
- Software Technical Leads guiding database technology selection and standards
Course Objectives
This course equips you to design, execute, and measure database optimization initiatives that improve application speed, ensure data consistency, and align with infrastructure cost-efficiency goals.
By the end of this course, you'll be able to:
- Analyze query execution plans to identify high-cost operations and bottlenecks
- Apply advanced Window Functions and CTEs to solve complex analytical challenges
- Construct optimized indexing strategies using B-Tree, Hash, and GIN index types
- Evaluate database schema designs against 3NF and denormalization performance trade-offs
- Implement transaction isolation levels to balance concurrency and data integrity
- Navigate complex join algorithms including Nested Loop, Hash, and Merge joins
- Measure database performance using system metrics and wait-event analysis tools
- Synthesize optimization findings into a comprehensive database performance audit report
Requirements & Prerequisites
Participants should have at least 2 years of experience writing SQL and a solid understanding of relational database concepts. Familiarity with basic JOINs, aggregations, and table creation is required. No prior experience with performance tuning or database administration is necessary, though a basic understanding of command-line tools is helpful.
