A web-based interface is provided for visually modeling a business-to-business or application integration process by selecting and associating predetermined process-representing visual elements. A customized, enterprise-specific executable software application (“dynamic runtime engine”) is automatedly produced by software running remotely. The dynamic runtime engine is created to include a generic application template, predefined “stock” codesets selected as a function of the modeled process, and a data profile codeset that includes input provided by the user for customizing the stock components for a specific integration process of a specific enterprise.
