Data Fusion of Geographically Dispersed Information: Experience With the Scalable Data Grid

摘要

Test and evaluation (T&E) professionals today often face the distribution of data they need to use over significant distances. Some of these data sources are too large for easy transmission because of costs, delays, losses, security, and administrative burdens. The Information Sciences Institute (ISI) has been working with the Joint Forces Command on its transcontinentally distributed battlespace simulations, and they have conceived, architected, implemented, and tested a system that uses the data in place. This has been characterized as a scalable data grid that uses data cubes for rapid and focused retrieval. It is necessary that these data be available in a timely manner, organized for ease of access, securely stored, and easily manipulated for data mining. Suggestions are offered listing T&E situations to which the scalable data grid approach would seem applicable.
