Dynamic Data Store for Distributed Situational Awareness (Phase II)

Physical Sciences Inc. (PSI) will develop a real-time, open architecture, data storage software component, and corresponding data model, as a key enabling element of a distributed common operating picture (DCOP) capability for the Integrated Combat System. The Dynamic Data Store (DDS) allows representation of all national, coalition, and adversary platforms and systems, their capabilities and status, as well as the sensor data and derived tracks fused and synchronized across the battle group. To allow seamless upgrade of both software capabilities as well as sensors and data types, the DDS design allows several forms of on-the-fly extension during combat system operation with minimal impact on the availability of the combat system. The DDS is designed to provide a highly generic interface to client components which access the data entities stored by the DDS. This interface mechanism allows efficient query, retrieval, and update to stored data objects with a small set of variant-based data structures, so that the interface is independent of the actual data schema (JC3IEDM) and will not need to be changed as the schema evolves.
