PostgreSQL and PL/pgSQL: From SQL Basics to Database Automation

Modern applications rely on robust, fast, and automated databases to handle complex business logic. PostgreSQL is one of the most powerful open-source database systems in the industry, and learning how to program directly inside it is a highly sought-after skill. In this text-based course, you will transition from writing basic database queries to developing sophisticated database automation. You will learn how to structure data, write optimized queries, and use PL/pgSQL to build reusable functions and triggers that enforce business rules directly at the database level. What you'll learn: - Understand core relational database concepts, schemas, and PostgreSQL terminology. - Write and optimize SQL queries using joins, aggregations, and common table expressions. - Develop reusable database functions and stored procedures using PL/pgSQL. - Implement triggers to automate actions and maintain data integrity during updates. - Work with modern JSONB data types to handle semi-structured data efficiently. - Apply indexing strategies and basic query optimization to improve database performance. The course begins with foundational database concepts and SQL syntax before guiding you through the procedural power of PL/pgSQL. You will read structured explanations and analyze real-world code snippets designed to build your practical database skills. This course is designed for beginners who want to learn database development from scratch, with no prior SQL or programming experience required.
