SQL databases now support semi-structured data such as JSON alongside traditional relational models.
The hybrid approach allows for storing rich nested data, adapting to evolving schemas, and joining structured and flexible data together.
Key points covered are JSON column types, querying nested structures, indexing for performance, and cross-database examples in PostgreSQL, MySQL, and SQL Server.
The article emphasizes the benefits of using JSON in SQL databases for various use cases such as dynamic user profiles, event logs, IoT sensor payloads, and more.
