At least one model synchronization map table is built that facilitates navigation between elements of business objects of a business object model and corresponding elements of an extensible markup language (XML) schema definition-based (XSD-based) model. The XSD-based model includes at least one XML schema and is generated from the business object model. The business object model and the XSD-based model are displayed in a dual-view editor. The dual-view editor enables a user to toggle between and independently edit the business object model and the XSD-based model. In response to independent edits made to one of the XSD-based model and the business object model within the dual-view editor, the elements of the business object model are automatically synchronized with the corresponding elements of the XSD-based model using the at least one model synchronization map table.
