Model–view–controller is a software architecture, currently considered an architectural pattern used in software engineering. The pattern isolates "domain logic" from the user interface , permitting independent development, testing and maintenance of each .Model View Controller...

 (MVC) framework where the Model and Controller are shared across platforms and the View is implemented for every specific platform and/or target architecture. It allows the development of both native and HTML5 web apps that share business logic and data code. The pattern enables cross-platform portability of business logic and data access code, (Model + Controller), while supporting full, native and/or platform-specific presentation (Views). This enables separation of the presentation layer, (View) from the application code (Model + Controller). This modification enables portability of application code across multiple platform targets.
