Canonical model

Imagine you have a lot of toys in your room. Some toys are similar to each other, like different colored balls or different sized toy cars. And sometimes you have different versions of the same toy, like two different teddy bears. Sometimes you might get confused about which toy you are talking about or which one you want to play with.

Now imagine you have a list where you write down the name of each toy and a description of it, like color, size, and shape. This list helps you keep track of your toys and makes it easier to talk about them with your friends or parents.

A canonical model is kind of like that list for computer programs. In computer programs, there are lots of different ways to organize data or information. But sometimes, it's helpful to have a standard way of organizing that information that is accepted by everyone. That's where a canonical model comes in.

A canonical model is a really organized way of defining and describing data or information. It helps computer programs talk to each other and understand each other more easily. So if two different computer programs need to share information, they can use the same canonical model to make sure they are both talking about the same thing. It's like having a common language that everyone understands.
