This paper describes the architecture of a heterogeneous distributed database management system called the Distributed Access View Integrated Database (DAVID). The DAVID system allows uniform access to distributed data stored in different DBMSs that support various data models. The system presents the users with a unified cluster data model and with a uniform high level query language (GSQL). Database heterogeneity issues such as external-to-conceptual view translation, view integration, query processing and the definition of a uniform data access language are presented in the context of the DAVID development.
