To translate one interface for a class into a compatible interface. An
adapter allows classes to work together that normally could not because
of incompatible interfaces by providing it's interface to clients while
using the original interface.

Examples
--------

-  DB Client libraries adapter
-  using multiple different webservices and adapters normalize data so
   that the outcome is the same for all
