Management of multiple representations in spatial DBMSs


Different representations of the same real world objects are often maintained in separated DBMSs because datasets are created and maintained for different purposes. When the links between these representations are explicitly defined and managed in a DBMS environment, data consistency and integrity can be significantly improved. Furthermore the quality of the data content can be improved because of update propagation and error checks between different data sets. This paper discusses important issues that need to be solved before a management system for multiple representations can be established. The paper addresses several important aspects related to maintenance of multiple representations, automatic interrelations between two and more representations of one real-world object and automatic generation of low-resolution representations from high-resolution. The results of a case study are described in detail. The paper concludes on topics for further research.
