Abstract

Integrity constraints of various kinds must be observed when creating or updating a database in order to preserve the semantics and the quality of stored data (Elmasri & Navathe, 2000). Within the scope of geographic applications, integrity assurance requires special attention from the designer, since most geographic applications use data that depend on spatial relationships (Egenhofer & Franzosa, 1991), thereby requiring the specification of spatial integrity constraints.
