Distributed Databases for Surveying

Abstract

Space related data is gathered in different places and by different services. Considerable duplication of effort to maintain the same data is obvious. The use of a distributed database management system to manage such data collections is proposed. Information and data collection have special characteristics which must be taken into account. They are expensive to update, but can easily be duplicated or transported from one place to another. Different users may produce or use the data and data may be an important asset for a user group. A distributed database may be adapted to such situations and most adequately suit managerial considerations. Users may maintain control over data of importance to them but nevertheless let other users gain access to it.
