PostgreSQL Fundamentals: Querying, Indexing, and Streaming Replication

Do you need reliable, performant data storage for your applications? PostgreSQL is a powerful, open-source relational database, and mastering its fundamentals is crucial for any modern developer or data professional. This course provides a solid foundation in PostgreSQL, moving beyond basic SQL to cover advanced data management techniques, performance optimization, and critical high availability features like streaming replication, ensuring you can build and maintain robust database systems. What you'll learn: * Understand the architecture of a relational database system and key PostgreSQL concepts. * Practice writing complex and efficient queries using advanced SQL features like Common Table Expressions (CTEs) and Window Functions. * Master indexing strategies (B-tree, GIN, GiST) and analyze query execution plans for performance tuning. * Configure user roles, permissions, and basic security settings to manage database access safely. * Apply transaction control (ACID properties) and ensure data integrity using constraints and views. * Configure and monitor streaming replication to achieve high availability and reliable data redundancy. We start with foundational definitions and setup, progress through data manipulation and complex querying, and conclude with crucial topics in performance optimization and database administration. The course emphasizes written explanations and practical SQL exercises. This course is designed for absolute beginners in database administration, developers new to SQL, and anyone needing a foundational understanding of PostgreSQL.
