Being good at problem-solving is one thing but to take your career to the next level, one must know how complex software projects are architected. Software design patterns provide templates and tricks used to design and solve recurring software problems and tasks.  Applying time-tested patterns result in extensible, maintainable and flexible high-quality code, exhibiting superior craftsmanship of a software engineer. Being well-versed in knowledge of design patterns allows one to spot brittle and immature code from miles away. The course goes to great lengths to lay bare the esoteric concepts of various design patterns before the reader and is replete with real-world examples and sample code.
The readership for this course is expected to be familiar with some object orientated language. The course examples and snippets are written in the Java language but folks with experience in other OOP languages should easily be able to follow the discussion and code intent.

<p>A facade literally means the front of a building or an outward appearance to hide a less pleasant reality. The facade pattern essentially does the same job as the definition of the word facade. Its purpose is to hide the complexity of an interface or a subsystem.</p>
<p>If you take a look around the amenities of current life, almost everything is a facade. When you press a button to turn on the room lights. The button is a facade that hides from you the complexities of electric power generation and distribution and magically lights up your room. The facade makes complex systems easier to use.</p>

<p>Formally the facade pattern is defined as  <b><i>a single uber interface to one or more subsystems or interfaces intending to make use of the subsystems easier</i></b>.

This lesson discusses how the interface to a complex system of interacting entities can be simplified by providing a front that hides the subsystem intricacies from the client.
