Practical PostgreSQL: Query Tuning, Indexing, and Design

Relational databases power the modern web, and PostgreSQL stands out as the standard for robust, scalable data storage. Whether you are building backend applications or analyzing complex datasets, understanding how to interact with and optimize a database is an essential skill. This course takes you from fundamental database concepts to practical query tuning. You will learn how to structure data, write complex queries, and ensure your database runs efficiently, culminating in a practical project where you design a realistic database schema from scratch. What you'll learn: • Understand core relational database concepts and PostgreSQL architecture. • Write efficient SQL queries to retrieve, filter, and aggregate data. • Apply modern indexing strategies to dramatically speed up query performance. • Work with advanced data types like JSONB for flexible, semi-structured data storage. • Practice query tuning techniques and analyze execution plans to identify bottlenecks. • Design and normalize a practical database schema for a real-world application scenario. The course begins with essential terminology and basic definitions before moving into hands-on querying, data manipulation, and optimization techniques. You will read through detailed explanations, study practical code snippets, and apply your knowledge through written exercises and a guided database project. Designed for beginners, aspiring backend developers, and data analysts, this course requires no prior database experience.
