Heterogeneous Distributed Information Management for the Infosphere (HDIMI)
Abstract
The HDIMI project is developing broadly applicable technology for information management in monitoring and control applications such as C4I and industrial control. The key technology is Active Views, an integrated set of mechanisms that provide uniform treatment of state, state change, and state history for arbitrary object types throughout a system. Active Views allow the construction of use-specific 'windows on the world' that provide the user with the information he/she needs, extracted from the vast pools of information available on the global infosphere. The source information can take such diverse forms as streaming video and conventional database structures, and can be filtered through a view function before presentation to the user of client application. The view function is defined as a composition of more basic functions drawn from an extensible library. When the source information changes, the corresponding change to the view (if any) is computed and delivered to the user or client application with specified quality of service. The resulting system, called Sonata, includes a CORBA-based distributed run-time environment, a COTS OODBMS for storing structured data, a continuous media server, and a graphical program development tool.
