A Geographical Extension to the Relational Datamodel

Abstract

Modern Command and Control information systems contain both alphanumerical and geographical data (e.g. maps). Efficient storage and retrieval of geographical information from a relational database is not possible with current technology. This report deals with this problem and presents a possible solution. The solution is based upon the extension of the relational model with some domain-types and database operators and uses special index- structures. Keywords: Data bases; Data base management; Relational databases. (kt)
