Extending Geographic Databases for a Query Language to Support Queries Involving Statistical Data F. Ferri, E. Pourabbas, M. Rafanelli, and F. Ricci   View Paper (PDF)   Return to SPATIAL DATA MANAGEMENT Abstract The concepts abstracted from reality and represented through the dimensions in a Statistical Database (SDB) support the user to use them in query formulation and processing. Instead, all those useful properties involved in a query that cannot be obtained through dimension/s in a SDB (for example, the concept of adjacency) can be presented in a Geographical Database (GDB). This paper presents a conceptual approach to allow the end user, working in a Geographic Database (GDB) environment, to use data cube stored in a Statistical Database (SDB). In this context, we need to extend the geographic data structure with some special “functional attributes”. They support links between the above-mentioned environments through geographic dimension/s always implicitly or explicitly present in SDB. Therefore, the main objective of this paper is to propose a solution to answer queries involving data stored in both environments in a transparent way to the user. Then, a query language to support the integration of multidimensional operators with geographic operators is proposed. Finally, the main characteristics of the proposed approach are illustrated through some examples.
