Design pattern is a general repeatable solution to a
commonly occurring problem . A design pattern is not a
finished design that can be transformed directly into code.
It is a description or template for how to solve a problem
that can be used in many different situations.
Object-oriented design patterns typically show
relationships and interactions between classes or objects,
without specifying the final application classes or objects
that are involved.

Design patterns deal specifically with problems at the
level of software design.
