Organizations usually store information in heterogeneous data formats and in various legacy databases and file systems scattered across the enterprise. Accessing relevant information in such a heterogeneous setting can be a daunting task because it requires the user to be familiar with different communication protocols as well as the nuances of various database softwares. And the user, in addition to retrieving the desired information from various systems, must then synthesize the information into a coherent whole. Eliminating these inconveniences requires the development of common data representations and the capability to transparently access information in a distributed heterogeneous system.
CERC has developed a tool called the Information Sharing System (ISS) to address problems arising in the management of replicated data, version and concurrency control, and change management in distributed databases. The ISS provides team members with a unified view of the distributed information as well as transparent, uniform, and easy access to this information. With the ISS, users simply specify the information they need without needing to know the source of the information.
