Introduction
MySQL version 5.7.8 introduces a JSON data type that allows you to access data in JSON documents.
SQL databases tend to be rigid in design. By its nature, the structured query language enforces data type and size constraints.
In comparison, NoSQL databases encourage flexibility in design. In these schema-less databases, there is no imposed structural restriction, only data to be saved.
The JSON data type in MySQL grants you the strengths of both of these systems. It allows you to structure some parts of your database and leave others to be flexible.
The first half of this article will design a database with JSON fields. It will step through using the built-in functions available to MySQL to create, read, update, and delete rows.
The second half of this article will utilize the Eloquent ORM with Laravel to communicate with the database. You will build an admin panel that supports displaying products, adding new products, modifying existing products, and deleting products.
