Data Abstraction is the process by which data and programs
are defined with a representation similar to its meaning
(semantics), while hiding away the implementation details.
Abstraction tries to reduce and factor out details so that
the programmer can focus on a few concepts at a time. A
system can have several abstraction layers whereby
different meanings and amounts of detail are exposed to the
programmer.
For example, low-level abstraction layers expose details of
the hardware where the program is run, while high-level
layers deal with the business logic of the program.
