Summary: Design patterns are important because they represent generic solution to a common problem. They are created in a way that solves the common task at hand, but more importantly provide a solution that is easier to maintain and enhance as the application evolves. Please note that the code I am covering in these examples is mostly from the DoFactory web site (not my own). I am covering these patterns to make developers aware of them and encourage everyone to find the pattern that matches his/her needs and apply it to a specific scenario. Please note that not every problem needs a pattern (in other words, do not over use them). Some patterns are similar; with experience you can hand pick the one that mostly suits your needs. In this case, we will cover the Facade Design Pattern. This pattern Provide a unified interface to a set of interfaces in a subsystem. Facade defines a higher-level interface that makes the subsystem easier to use.
Methodology of the development of example: Good coding standard and simplified design.
Technology Used: C# 4.0
