This course teaches you how to work with PostgreSQL, one of the most powerful and popular open-source relational database systems. Covering everything from writing SQL queries to advanced features like JSON support, indexing, and performance tuning, this course is designed for beginners who want a solid foundation in PostgreSQL. By the end, you’ll be able to design, query, and manage PostgreSQL databases confidently for real-world applications.

What Will I Learn?

  • Understand what makes PostgreSQL unique among relational database systems
  • Write basic to advanced SQL queries for retrieving, inserting, updating, and deleting data
  • Design well-structured database schemas using keys and relationships
  • Combine data from multiple tables using different types of joins
  • Use aggregate functions and grouping to summarize and analyze data
  • Work with PostgreSQL-specific features like JSON/JSONB, arrays, and window functions
  • Understand indexes and use EXPLAIN ANALYZE to optimize query performance
  • Apply everything learned by designing and querying a database for a real-world project
