Abstract: A computer apparatus and method are provided for visually mapping fields of various electronic forms to a common object model. The forms may then be dynamically completed via a runtime engine that retrieves mapping data from a relational database and uses the mapping data to automatically populate corresponding fields of the forms without manual input by the user. Specifically, a visual mapping tool displays the objects of the common object model as well as the fields of a form to be mapped. A user drags and drops one or more of the displayed objects into a mapping area, and drags and drops a field to which the one or more objects are to be mapped. The user also identifies a type of association between the selected objects and the field. A mapping entry is then generated in a map file to map the selected objects to the field.
