Introduction to Database Integrity: Challenges and Solutions

Abstract

Data properties should be seen from the point of view of being as independent as possible from the representation model. In this way, data properties can be analyzed from two different perspectives: from the real world and the database world. A real world data property of a given class may be mapped into a different database class of properties due to materialization issues. This depends on the database paradigm and on the adhesion of the DBMS to that paradigm.
