ON DISTRIBUTED PERSISTENT OBJECTS FOR INTEROPERABLE DATA STORES

The merging of distributed computing and object-oriented technology ha s resulted in novel ways to design and develop modern and aggregate ar chitectures of databases. Distributed object management has emerged as the core technology of this trend, and the CORBA specifications attem pt to manage such environments. In this paper, we examine the CORBA ar chitecture, both as a distributed object management framework as well as a service to interoperate persistent objects. We report on using tw o off-the-shelf DBMSs (ONTOS and UniSQL) as a testbed for a feasibilit y study.
