In
technology world MVC stands for Model View Controller; MVC
is an architectural design pattern to develop the software. MVC design pattern is
widely used to develop a web application.
Model:
Model represents the real life entity such as customer. Model consists of
application data, business rules, logic and functions.
View:
View represents the model data on UI or page (web application). View is actual representation
of data in user friendly format. View present data in terms of user controls, charts,
diagrams etc.
Controller:
Controller is mediator between Model and View. It takes model data and
represents it on the view. It could also take input from the user and send to
the model for further processing or to take action on it by model.
This
design pattern is exists since 1970. The MVC pattern is widely used with
programming languages such as Java, Smalltalk, C, and C++. Now Microsoft Web Developer
can easily integrate this design pattern with Asp.Net application using RAZOR
or ASPX engine.
Now
next question comes into your mind is that why should I use MVC or what are the
advantages of using the MVC design pattern?
Following
are the advantages of using MVC pattern
- Separation of concerns: View is only responsible for displaying data on UI. No business logic is tightly integrated in view. Controller is responsible for processing user requests. Business logic now resides in a model.
- Unit Testing: You can test your business logic using Unit test tools such as NUnit, xUnit etc.
- TDD: TDD stands for Test Driven Development, In TDD approach developer will always writes test first for a module or business logic. This approach is helpful in early detection of an issue in development.
