Multidatabase Interoperability

The main purpose of this paper is to provide a brief review of the most current work in the area of multidatabases. We first define the problem and argue that multidatabase research will become increasingly important in the incoming years. We then outline basic research issues in this area and concentrate on issues related to schema integration and semantic heterogeneity, and multidatabase transaction management. The review is not intended to be comprehensive and in spite of our effort to remain objective in selecting review topics, probably reflects the author's biases to some extent.
