Customize with Code
The ultimate power to customize on demand
Because Force.com Builder makes it possible for business users and administrators to do most customizations, IT and skilled developers are free to focus on the complex customizations that do require coding.
For complete freedom to customize, salesforce.com provides toolkits for most of the common programming languages, including Java, VB.NET, C , .NET, or open-source languages. For developing highly visual and interactive applications that make the most of the browser’s capabilities, there’s also an AJAX toolkit. Regardless of how customizations are created or how extensive they are, they are preserved during upgrades, without any effort on the customer’s part.
