What is the concept behind a strong technology framework? MVC is a pattern of software architecture/development that divides an application into three interrelated components: Model, View, and Controller. 
 
 MVC is designed and implemented to improve maintainability and provide Separation of Concerns, a key principle in computer science.

MVC is a pattern of software
architecture/development that
divides an application into three
interrelated components: Model,
View, and Controller.
MVC is designed and implemented
to improve maintainability and
provide Separation of Concerns, a
key principle in computer science.
examples of MVC frameworks include:

3. Norwegian computer scientist Trygve Reenskaug is credited with conceiving of MVC
as a design pattern in the late 1970’s while visiting Xerox PARC*.
*PARC is credited with developing laser printing, Ethernet, the modern personal
computer, GUI, object-oriented programming, and much more.

4. M: Model
The Model is responsible for managing the the data, logic, and rules of
an application.

6. V: View
View is what's presented to the users and how users interact with the
application. The view is made with HTML, CSS, JavaScript and often
templates, e.g. .liquid and embedded-ruby, etc.

8. The controller accepts input and converts it to commands for the
model or view.
C: Controller

11. A controller can send commands to the model to update the model's state
(e.g., editing a document). It can also send commands to its associated view
to change the view's presentation of the model (e.g., by scrolling through a
document).
A model stores data that is retrieved to the controller and displayed in the
view. Whenever there is a change to the data it is updated by the controller.
A view requests information from the controller. The controller fetches it from
the model and passes it to the view that the view uses to generate an output
representation to the user.
