Data modeling by examples with django 4.0 Models Part 1

Описание: In this video, I demonstrated concrete examples of data modeling from a business standpoint to solving problems. I modeled my physical entities/models using the Django model that enables fast schema creation and modification. I explained concepts such as business objectives and business requirements. What are the differences; demonstrate creating table constraints and what are they, indexes; when should you consider having an index versus having more indexes? I used validators to validate attributes when inserting data into the database. Where do the validations come from, and why are they necessary for your tables?
