Description
Welcome to Part 55 of our PostgreSQL Full Playlist! 🎥 In this video, we dive deep into one of the most powerful data types in PostgreSQL — JSON and JSONB.

📌 What You’ll Learn:

The difference between json and jsonb types
How PostgreSQL stores and processes JSON data
Practical examples: inserting, querying, and updating JSON fields
Using operators
Powerful indexing strategies using GIN, BTREE, and expression indexes
Working with jsonpath queries for complex lookups
Handling edge cases like Unicode, nulls, and nested structures
Real-world best practices and performance tips for working with semi-structured data

PostgreSQL’s support for JSON is incredibly robust, allowing developers to handle flexible data formats while still benefiting from SQL power.

Whether you're a backend developer, database admin, or student, this video will equip you with essential skills for modern data modeling using JSON in PostgreSQL.
