A CORBA based architecture for heterogeneous information source interoperability

Abstract

Computational environments are characterized by islands of information. Data is spread throughout the computational system nodes and is controlled by several different data management systems. However, application programs require an integrated view of such data. Thus, it is necessary to build bridges to connect these information islands. Heterogeneous database systems, especially those object-oriented based have been referred to as one of the most viable solutions to the problem of system integration in heterogeneous distributed environments (HDDS). The implementation of such systems is still challenging. This work presents an experience of implementing one of such systems using the CORBA standard as the communication basis in an architecture that uses the concept of HDDS.
