Using Global Snapshots to Access Data Streams on the Grid

Data streams are a prevalent and growing source of timely data. As streams become more prevalent, richer interrogation of the contents of the streams are required. Value of the content increases dramatically when streams are aggregated and distributed global behavior can be interrogated. In this paper, we demonstrate that access to multiple data streams should be viewed as one of deriving meaning from a distributed global snapshot. We de ne an architecture for a data streams resource based on the Data Access and Integration 2] model proposed in the Global Grid Forum. We demonstrate that access to streams by means of database queries can be intuitive. Finally, we discuss key research issues in realizing the data streams model.
