What are Drupal Entities?

[@abclef]

Thanks! This explain clearly! In short, entity system is a OOP thing, if you're familiar with .NET, Entity is the Object base class in drupal.

In your diagram of an Entity at 6:10, if "properties" are, by definition, applicable to every bundle of the entity type, shouldn't the properties you have listed fall under Node and not under Article? Leaving only the fields to exist under Article? Thinking about this from a programing perspective, if I were to define an entity type in code, I would have to define the properties that would be a mandatory part of every every bundle that is subsequently created, almost as if we're enforcing an Interface contract.

That's a good suggestion. Thanks. More like a standard UML class model. Which, would make even more sense for Drupal 8+ where entities are typed, e.g.) `Node` extends `Entity` and `User` extends `Entity`.

i'm building a review site with review, maker, location custom content types. they are all related. i'd like to create views of makers and locations etc. i'm not sure if entities is what i'm looking for? also, using an entities approach, does that mean i can put multiple content types on one create content form?
