Abstract

An application program may include application modules. One or more of the application modules may each include a dynamic component and static component. The dynamic components and the static components may be configured to function according to an initial set of requirements for the application. A dynamic component generator may receive a new set of requirements for the application and generate updated dynamic components to replace the current dynamic components. The updated dynamic components may be configured to function according to the new set of requirements.
