Policy-based design
Policy-based design is like playing with Legos! You know how you can make different things using Legos because you have different shapes and colors of Lego blocks? Policy-based design is like that, but instead of making toys, we make software!
In policy-based design, we have different building blocks called policies. These policies are like rules that tell the software what to do. For example, let's say we're making a software that sells shoes. We can have a policy that determines the price of the shoes, one that determines the color of the shoes, and one that determines the size of the shoes.
These policies can be mixed and matched to create different combinations of shoes. So, we can have a policy for expensive shoes with blue color and size 10 or a policy for cheap shoes with red color and size 6.
The best part about policy-based design is that we can easily change these policies without changing the whole software. So, if we want to change the price policy from expensive to cheap, we don't have to change anything else. This makes it easy to customize the software to fit different needs.
In summary, policy-based design is like playing with Legos where we have different policies that act as building blocks to create software. It makes it easy to customize software without changing everything else.
