Abstract: The customization system receives an application model that contains one or more elements stored in a database. The customization system receives a modification to an element of the application model. The customization system stores the modification to the element separately from the application model such that the application model is accessible in either a modified or unmodified state. Thus, multiple third parties can make changes to the same application model elements and business logic without causing conflicts with each other. In addition, updates and patches to the enterprise resource planning system can be applied with less likelihood that the customizations will be negatively affected.

Abstract: A computer program based method is described for creating models using gestures. On an input device, such as an electronic whiteboard, a user draws a gesture which is recognized by a computer program and interpreted relative to a predetermined meta-model. Based on the interpretation, an algorithm is assigned to the gesture drawn by the user. The executed algorithm may, for example, consist in creating a new model element, modifying an existing model element, or deleting an existing model element.
