METU interoperable database system
1995
SIGMOD record
Preserved Fulltext
METU INteroperable Database System (MIND) is a multidatabase system that aims at achieving interoperability among heterogeneous, federated DBMSs. ...
MIND architecture is based on OMG distributed o b j e ct management model. It is implemented on top of a CORBA compliant ORB, namely, ObjectBroker. ...
These properties provide the means to handle heterogeneity at the database level. Thus CORBA provides for an infrastructure for implementing a multidatabase system. ...
