Abstract

We discuss the integration of a variety of data and information sources in a Physician Workstation (PWS), focusing on the integration of data from DHCP, the Veteran Administration's Distributed Hospital Computer Program. We designed a logically centralized, object-oriented data-schema, used by end users and applications to explore the data accessible through an object-oriented database using a declarative query language. We emphasize the use of procedural abstraction to transparently integrate a variety of information sources into the data schema.
