This means that the merging operation, when it succeeds, is both associative and commutative, i.e., that the merge of schemas is independent of the order in which they are considered -- a property not possessed by existing methods. The technique is interactive in that users made assertions about the relationships between the nodes of the schemas to be merged. These assertions are then considered to be elementary schemas, and are combined with the schemas using precisely the same merging operation. The technique is general and can be applied to a variety of data models. It can also deal with certain cardinality constraints that arise through the imposition of keys. A prototype implementation, together with a graphical interface, has been developed.
