DATA-BASE MANAGEMENT SYSTEM TECHNOLOGY AND GEOGRAPHIC INFORMATION SYSTEMS

This discussion focuses on the data base management systems (DBMS) issues involved in developing distributed geographic informations systems (GIS) from preexisting, independently, developed components. The paper discusses limitations of conventional DBMS technology, and describes the support of complex data objects. Data distribution and communication is considered, as well as the integration of preexisting systems. The development of hybrid GIS architectures is noted, as well as the current effort to develop object oriented DBMSs that support complex objects. The development of structure transfer protocols is a basic requirement for the wider applicability of this technology. To build a distributed information system from independently implemented, preexistnting systems, physical and semantic integration issues must be addressed.
