So imagine you have a toy farm with animal figurines, like cows, horses, and pigs. Each animal is part of a specific area of the farm, like the barn or the pasture.
In a hierarchical model-view-controller, you can think of the model as the farm itself, with all its areas and animals. The view is like the way you see the farm - when you look at it from above, you see all the areas and animals in their locations. The controller is like the person who moves the animals around and decides where they go.
But in a hierarchical model-view-controller, there are different levels of detail. For example, if you zoom in on the barn area of the farm, you'll see specific animals inside - this is a lower level of detail. If you zoom out to see the whole farm, you'll see all the areas and animals in one view - this is a higher level of detail.
So in a hierarchical model-view-controller, you can move between these different levels of detail easily. You can focus on just one area of the farm, like the barn, or look at the whole farm at once. And you can control where the animals go, like moving cows from the pasture to the barn.
Overall, a hierarchical model-view-controller helps you understand different levels of detail in a system, like a toy farm, by organizing everything into layers and giving you control over each layer.
