MVC web application development India

Model-View-Controller (MVC) is architectural design pattern for interactive web design applications of software systems that separately defines each layer. The interactive application is arranged in three different layers: Model, View and Controller. Using this style or pattern software is separated into model representing core functionalities, the second module is view that is used to display model to users and controller lets the users control the model. Model or application model consist of data representation and business logic; second module is for views that offers interface for user input and third is controller that is used to dispatch request and control flow. This programming model and implementation infrastructure allows developers to use the application source code without changing in different client-server environment. Since model, view and controller are used in single, non-partition space they can be easily deployed.

Ruby on rails technology uses this model view controller (MVC) architectural design framework fore creating database driven websites using Ruby programming language. MVC reduces code complexity by avoiding developers to write code again and again that is code redundancy. All this is achieved by making complex web application easy to handle by dividing the web application into simple layers.

This programming model or methodology is not suited for systems with many domains but is well suited for single domain system because of its simplicity. Modification is easier as model, view and controller are separate. This allows easy modification of data and reduces code duplication as all the three data behavior, data presentation and data control are separate.

Application operates on this domain specific information Model, database interaction and business logic are handled by the model, also multiple views may exist for single model (these are user interface elements), these are actual HTML code that are displayed in the browser and controllers manage web server interaction, these are user actions that may lead to changes in the existing model.

MVC makes the complex web application developmentsimple to mange and implement. Controller lies between model and the view and is responsible for extracting objects from database using model and giving it view for user. It is view that takes data given by the controller and produces the HTML output for the web browser, at the same model and controller are set free to do their specific jobs while view is busy generating HTML codes. The view is added sum of HTML and Ruby and adds dynamic content from model without relying on third party for formatting. Rail framework captures HTML and sends to web browser. Ruby on Rails development takes these concepts and bundles into single pack.
