A web-based data form enables modifications made to values in the data form to be dynamically implemented in a data source. Form fields of the data form are associated with items in the data source using data binding information. Data from the data source is transformed into intermediate code using Extensible Stylesheet Language Transformation (XSLT) code. Form controls of the data form are instantiated using the intermediate code. Hypertext Markup Language (HTML) is generated from the intermediate code including the form controls.
