MVC & MVVC
What is MVC?
MVC is software architecture design pattern. MVC stands for
Model , View and Controller , it is a server side design pattern . MVC pattern is used
by well-known frameworks such as Ruby on Rails, Apple ios Development, ASP.NET
MVC, etc . It has 3 main component.
- Model.
- Controller
- Views
It like as a triangle where all part can communicate with
each other.
Model
Model represent the shape of the data and business logic and
also it defines the business rules for data. It contain the pure application
data. In J2EE javabean provide Model.
View
View display data using model to the user. It knows how to
access the model’s data but it does not know what this data means. It is
script-based templating systems like JSP, ASP, PHP and very easy to integrate
with AJAX technology. In J2EE JSP5 provide view.
Controller
Controllers are responsible for controlling the flow of the application execution. When you make a request to MVC application, a controller is responsible for returning the response to that request. In J2EE controller servlet provide controller.
What are the advantage of MVC model??
- Support for asynchronous request.
- Modification does not affect the
entire model.
What are the disadvantage of MVC model??
- Increased complexity.
What is MVVC ??
MVVM is software architecture design pattern. MVVM stands for Model View- ViewModel. It is used
on all XAML plat There are three core components in this pattern, they
are model, view, and view model. Each
component have separate role and decoupled from each other.
These components work on independently. View
know about view-model and view-model know about model but model unaware of
view-model and view-model unaware of view. This
allow, developer-designer workflow. When the UI XAML is not tightly
coupled to the code-behind and
Model
Implementation
of the application’s domain. It include data model along with business and
validation logic.
View
View represents the user interface components such as
CSS, jQuery, HTML, etc. View binds to
observable variables and actions exposed by the View-Model in a flexible way.
View-Model
It is responsible for preparing the data for the
UI/View and wrapping the model and
preparing observable data needed by the view Act as intermediary between model
and view.
What are the advantage of MVVM model??
- Components to be swapped.
- Internal implementation to be
changed without affecting the others.
- Components to be worked on
independently.
- Isolated unit testing.

It increases application testability. MVVM is
used by WPF, Caliburn, Silverlight, nRoute, and more.
