 Posted by Niladri.Biswas on 11/29/2012 | Category: Design Pattern & Practices Interview questions | Views: 3141 | Points: 40

A design pattern is a core of a solution that has been applied successfully in multiple environments to solve a problem that recurs in a specific set of situations. It is an effective means to convey/communicate what has been learned about high-quality designs. The result is:

– A shared language for communicating the experience gained in dealing
with these recurring problems and their solutions.

– A common vocabulary of system design elements for problem solving
discussions. A means of reusing and building upon the acquired insight
resulting in an improvement in the software quality in terms of its
maintainability and re-usability.
