How to remove all special characters from String i Difference between Comparison QuickSort and Non Why Static Code Analysis is Important? Facade doesn't changes the domain model of the other subsystem, while Adapter does.
This is the key difference. That's why you combine these two when you create an Anticorruption Layer. Let's say you have subsystem which you want to use, but you don't want its domain model to muddle your domain model. What would you do? You'd create an Anticorruption Layer. You first create a Facade, that simplifies accessing the interface for the subsystem, and then adapters for the domain objects used in that interface remember the facade still holds the domain model for the other subsystem , so it conforms to your model.
Many design patterns can be used in domain modeling. This is true for Facade and Adapter design patterns, as well.
Although the difference between these two patterns might not be clear in "design pattern" realm, it's more clear in "domain modeling" realm. I have noticed that the term Adapter is sometimes used to describe what is in fact a Stategy , maybe because the word is more expressive.
For example, in Zend Framework , all the Adapter classes are in fact implementations of the Strategy pattern, because they only wrap native code behind classes, to have several behaviours.

Great analogy using remote control. Adapter pattern explanation is OK, but it would be great to come up with the same kind of analogy. Excellent analogy indeed! Khnle - Adapter pattern in action: upload. Khnle - added in an Adapter analogy based on personal experience. Eric - thanks for the inspiration and great pic! BalusC - good call on the real world example. BalusC - I like your example too. Luckily I know Java. Eric Petroelje - A picture is worth thousand words :- awshepard - if I didn't programming, I now can follow you explanation too :- — Kevin Le - Khnle.

Facade: Key takeaways : from journaldev article by Pankaj Kumar Facade pattern is more like a helper for client applications Facade pattern can be applied at any point of development, usually when the number of interfaces grow and system gets complex.
Adapter makes two existing interfaces work together as opposed to defining an entirely new one Adapter and Facade are both wrappers; but they are different kinds of wrappers. The intent of Facade is to produce a simpler interface, and the intent of Adapter is to design to an existing interface Have a look at sourcemaking article too for better understanding.
