MVC Web Development Framework

What is Web Development Framework?

There is a huge number of server-side scripting languages, using them we can create web applications. Almost the scripts are full-fledged programming language and featured with Object Oriented Programming Systems. Popular of them are Java, PHP, Python, Ruby,Perl. At the early age of web the applications were built on conventional logic and components, are not organized or not reusable. As the next generation, web development technologies came into existence the requirement of frameworks increased.A need for such a tool was very important as they are time and cost efficient.

Now we have many frameworks with huge communities. Frameworks are the collection of basic building blocks and reusable code in an organized manner where maintenance and development both are painless processes. They implement code re-usability, inheritance, security, abstraction, accessibility, integrity, reliability, readability, maintainability in our applications. Now we are able to develop very robust applications in very less time. frameworks are enriched with various libraries and plugin. They also provide flexibility to extend the functionality of the core. Almost the framework is based on Model-View-Controller or MVC development pattern.

What is MVC?

MVC is a software architectural pattern, which provides a modular structure to an application and application is layered into Models(M), Views(V) and Controllers(C).

MODEL

Model is a layer where all the data building logic is present. This layer is abstract from direct access. We write or database queries and fetch and format data in this layer with given parameters. This layer is a central layer of all three.

VIEW

A view is a presentation layer. We see the desired results here in our browser. The user directly communicates with forms and perform actions and submit inputs. This is an end user layer where HTTP response displayed and request triggered by user actions.

CONTROLLER

A controller is an intermediate layer and create a pool between Model the data logic layer and View the representational layer. It collects user actions based on URI and parameters. Routing and reverse routing happen here.

Advantages of MVC Frameworks:

  1. Fast and quick development of complex web-applications.
  2. Collection of Plugins are available for most of the general purpose activities.
  3. Easy maintenance and debugging. Frameworks provide debugger kit , that eases the debugging process.
  4. MVC provides a modular structure to application that is why MVC based applications are flexible and robust.
  5. Most of them provide Database manipulation library, so no need to write custom and complex queries very often.
  6. Inbuilt security and migration features.
  7. Most of them come with a command-line interface to generate code-snippets and modules.
  8. They create SEO friendly URLs to easy for search engines to recognize your application urls.
