A domain model is like playing with toy blocks. Imagine you have lots of different blocks in different shapes and colors. You can use these blocks to build something cool, like a tower or a castle.
In the same way, a domain model is a way of organizing all the different parts of a bigger thing, like a website or a system. It helps you make sense of all the different parts and how they fit together.
Just like with toy blocks, you can use a domain model to create something that makes sense and works well. It helps you understand what each piece does, how they all work together, and what the whole thing is supposed to do.
