PostgreSQL Foundations: Database Design and SQL Essentials

Data is the backbone of modern technology, and PostgreSQL is one of the most powerful and flexible tools for managing it. This course provides a structured path to understanding how relational databases work and how to interact with them effectively using industry-standard practices. You will progress from understanding basic database concepts to writing sophisticated SQL queries and designing robust data structures. By the end of this course, you will be able to manage real-world data scenarios and build the backend foundations required for professional software development. What you'll learn: - Understand relational database theory, ACID properties, and key terminology - Write SQL queries to create, read, update, and delete data efficiently - Design optimized database schemas using normalization and relationship mapping - Apply advanced techniques like joins, subqueries, and window functions - Utilize modern PostgreSQL features such as JSONB for semi-structured data storage - Optimize query performance through indexing and execution plan analysis The course begins with foundational definitions and installation concepts before moving into hands-on SQL syntax and complex data modeling. You will learn through detailed written explanations and code-based exercises designed for immediate practical application. This course is designed for absolute beginners with no prior database experience, as well as developers looking to solidify their SQL skills. No previous programming knowledge is required.
