Thinking Abstractly
Abstract Models

Data Abstraction
A method that allows us to clearly see how a data object is used from the details of its construction.

Decomposition
This means to break programs down into smaller steps that are easier to deal with. This means they are quicker to be dealt with.
Abstraction vs Reality

Nature of
An abstraction shows just the essential information and allows for problems to be solved with more ease. It also allows you to clearly lay out how your going to solve an issue without needing to deal with complex issues.
