AN EXTENSIBLE VIEW SYSTEM FOR MULTIDATABASE INTEGRATION AND INTEROPERATION

Multidatabase integration and interoperation facilitates the developme nt of advanced applications built on top of heterogeneous database man agement systems (DBMSs). In this paper, we describe an extensible view system, the Zeus View System (ZVS), that supports multidatabase integ ration and interoperation. Our approach is based on multiple levels of abstraction through the notion of views. The ZVS has an innovative de sign that uses the Common Object Request Broker Architecture (CORBA) a s the infrastructure for distributed object management. The ZVS is pro totyped in a large-scale distributed computing environment. Our experi ence with the implementation of the prototype is presented. (C) 1995 J ohn Wiley & Sons, Inc.
