This paper presents a new approach combining multi-representation databases with the generalisation and update process. It leads to a tightly integrated model, which is implemented as a part of the existing cartographic GIS axpand. The approach is based on the mathematical concept of relations and, in particular, on the three different types of relations: intra-resolution, inter-resolution and up-date. Intra-resolution relations allow the representation of relationships between features within one resolution. Examples are partitions, neighbourhood and topology. The inter-resolution relation represents the relationship between features of different resolutions. This originates from a generalisation or matching process. The update relation describes temporal changes of features. After a detailed theory about the introduced relation types the paper continues with a discussion of their similarities and differences with focus on implementation in a multi-representation database. Finally some exemplary results of the integrated model are presented.
