Samenvatting

When the consistency of data is ascertained by constraints the maintenance of information systems becomes problematic. Geographical Information Systems are typical examples of such systems. Constraints introduce relationships among the elements of the data structure. This results in a huge complexity causing much additional effort when mutating the data. A modular approach enables to gather the relationships inside each module, while limiting the relationships among the modules. As a result the development and maintenance of massive systems becomes much more transparent. As a part of a series on data management, this article discusses elements of the above aspects.
