The document outlines the implementation of a Netflix clone using Codename One, detailing the entity model for content management. It includes classes for 'Content' and 'Media', with fields for UUIDs, names, descriptions, and media related data using Java annotations for ORM. Additionally, it discusses video qualities and provides data transfer object (DTO) definitions for handling content efficiently.

Now that we know Lombok basics we can move on to the server
The code is mostly mock code
We’ll start with the entity model code first

UUID Keys
Strings as keys are important, they eliminate scanning attacks
JPA lets us use the UUID class and the rest is pretty much seamless
This could be costly for RDBMS inserts
Unless you’re doing millions of inserts this shouldn’t be a problem
