What is Object Decomposition?

Question

I was trying to understand what object decomposition means and read a lot of stuff on internet but every resource talks in terms of lots of keywords that i couldn\'t understand.

Answer 1

Imagine, you have Car object. It is very large object, hard to support. You break this objects into smaller responsible for some part of the problem domain:

• Engine
• Сabin
• Boot
• ...

That's the decomposition, each of that objects can be broken again, like Cabin consist of Board, Sits, Wheel... Or probably Board consist of Wheel and other parts. Etc.
