PostgreSQL JSON and JSONB: Practical Data Management

Modern applications frequently handle semi-structured data, making JSON support in relational databases essential. This text-based course guides you through storing, querying, and managing JSON and JSONB data directly within PostgreSQL. You will start by mastering foundational terminology and structural differences between standard text JSON and binary JSONB. Through clear written explanations and practical SQL code snippets, you will learn how to extract nested fields, transform document structures, and build hybrid database schemas that combine relational power with document-store flexibility. Key topics covered include: • Understand foundational concepts of JSON syntax and native PostgreSQL data types • Compare storage trade-offs between standard JSON and binary JSONB • Query nested document properties using operators and JSON Path expressions • Index JSONB columns using GIN indexes to optimize search performance • Modify, update, and aggregate semi-structured data within SQL queries • Apply modern functions to transform JSON data into relational rows and vice versa. The material moves step-by-step from core definitions to practical indexing strategies and complex data transformations. This course is designed for beginners, backend developers, and database administrators, requiring only basic SQL knowledge.
