Abstract
In recent years it has become apparent that large centralised databases are not the universal panacea for all data management problems within large organisations. It was this dissatisfaction, coupled with the simultaneous micro- and mini-computer explosion, which acted as a catalyst for research into distributed database management systems. The primary objective of distributed database technology is to provide logically integrated access to the corporate data resource, while at the same time allowing the data to be physically distributed across a number of nodes in a computer network. In virtually all cases, the end-user view of the distributed database is relational, even though the underlying local database management systems may support network or hierarchical data models. This paper examines the state of the art of distributed database technology, with particular reference to the use of relational technology.
