Abstract

A fundamental concern in hospital information systems is the integration of information across heterogeneous subsystems at the data level. Consistent data replication is a central problem to be solved in this domain. The specific requirements and problems for integration of information within hospitals are discussed and a software architecture which has been designed according to these requirements is presented. The purpose of this paper is to study the problems and solutions of propagation of information updates across heterogeneous subsystems within hospitals. The general structure of the presented architecture is based on the reference architecture for federated database systems (Sheth and Larson 1990) and adapted to the specific demands on integration of replicated information within hospital information systems. This architecture is the basis for algorithms that restore the integrity of replicated information when changes occur. A prototype implementation is discussed.
