MVC Architecture

Hi Folks, Today I’m writing about MVC the MODEL, VIEW, CONTROLLER in Force.com application development platform. MVC is basically an Architecture Pattern which has some separation of concerns, in a Software.

Separation of Concerns means that classifying a Module in Sub-Modules which are integrated and interactive to each other.


Components

A Model basically manages data and enforces rules and validations on the data, currently in context. It’s a central component of the design pattern.

A View is your HTML/Javascript based representation of your data pulled from your Model. It can be a chart or some tabular formatted page to view information.

A Controller is a conveying medium between model and view which helps view to show data by pulling it from model. It basically accepts inputs and converts into instructions or commands to model or view.


Working

A model stores the data retrieved by the controller and displayed in the view.

A view generates new outputs for the user based on the changes in the model.

A controller sends commands to model to change the state or it can send commands to view to change the representation of the model.


Benefits

There are two key benefits of MVC design pattern that we can attach multiple views to a model to show data in different ways. And we can change the way that a view responds to an input by a user, without changing the view’s presentation.

So this is it for now and as we move ahead with our topics we’ll learn more about the MVC architecture pattern. I’m hoping that this article will help you to know a basic about MVC.

Force.com Applications

Hi Folks, Today I’m writing about the Force.com Applications for Salesforce.com. Developing an application on force.com has a defined process. This process goes as -  We can develop our application in Developer Edition Org. After being developed an application must be tested in a Sandbox. Since it’s a tested application it must be submitted for the Security Scanner reviews. Scanner scans our application for security, complexity and other issues. If our application gets a “No issues found” result then only it can be pushed on App Exchange. App Exchange is a marketplace for force.com applications. App Exchange is just like Google App Store. From the App Exchange we can download and install applications directly into our Salesforce.com CRM org.
