C4 model (software)

C4 Model is like a map which helps people to understand how a software application works. Think of it like a treasure map, where you see the treasure, the path you need to take to get there, and any obstacles in your way.

In the same way, C4 Model shows you different levels of a software application, like its big picture, its overall layout, its components, and how those components interact with each other.

Imagine building a castle with Lego blocks. You first need to have a plan, which shows the overall shape of the castle. This is called the 'System Context' in C4 Model. It helps you understand how the components of the software application are connected to the outside world.

Next, you need to create individual Lego blocks, which represent a specific function or feature of the castle. This is called the 'Container' in C4 Model. It helps you understand how different parts of the application work together.

Finally, you need to add details and decorations to each individual Lego block to make it look like a real castle. This is called the 'Component' in C4 Model. It helps you understand the inner workings of each individual part of the application.

In summary, C4 Model is like a map that helps people to understand how a software application works by showing them different levels like the big picture, overall layout, components, and how those components interact with each other. It's like a Lego castle, where you need to have a plan, create individual blocks, and add details to make it work.
