Schema-dominant mapping user interface

摘要

A scalable graphical user interface that may be used to map two or more schemas is provided. Elements of a dominant schema are displayed in a first column. Elements of a subordinate schema are displayed in a second column. A user may drag elements of the subordinate schema to a third mapping column and position those elements next to mapped dominant schema elements. A user can quickly and conveniently determine a relationship between mapped elements by selecting an element from the dominant schema and identifying one or more elements in the mapping column that are located next to that element.
