Apex and Visualforce

(Redirected from Apex Code and Visualforce)

You can extend your Force.com applications beyond the boundaries of the Application Framework with Apex and Visualforce. Apex is the world's first on-demand programming language. You can use Apex to extend the functionality of your applications with extensive logic implemented through triggers. You can create Apex classes for optimal standardization and code reuse. Visualforce gives you the ability to easily reshape the presentation of your Force.com applications, and that's only the beginning. You can use Visualforce pages to combine data from multiple Force.com objects, to blend data from web services into your applications, or to implement a robust Web 2.0-style interface for users.

Visualforce

Visualforce pages deliver the ability to create custom pages for your Force.com applications. Visualforce pages includes a set of tags to describe a variety of rich components into your page design. These components bring the full power of the Force.com meta-data driven platform to your pages, while giving you complete freedom to design pages to suit your specific user interface requirements. Visualforce pages run with the help of controllers, which provide the functional links between the page interface and the underlying data. You can use standard controllers which represent any Force.com data object, or create your own custom controllers for more flexible data access to an expanded range of data sources.

Apex

Apex is the world's first on-demand development language. Apex enables you extend the functionality of your Force.com applications with a robust procedural language. You can use this language to create triggers, which fire when any user performs certain data operations. Apex can also be used to create classes, which can be called from other classes and triggers, enabling productive code reuse and standardization. You can expose any Apex class as a Web service by simply adding a few keywords to the class.
