This paper describes the implementation of a Relational
Database Management System(RDBMS)-based data store
for object-oriented data. It is designed to support trans
actional operations needed to support the use of various
protocols for maintaining the consistency of replicated data
stores. A subset of Object Deﬁnition Language (ODL) and
Object Query Language (OQL) standard is used for ob
jects’ state storing and to perform queries respectively. The
service does not depend on the underlying RDBMSs, and
it allows object replication.
