High-Performance GRID Stream Database Manager for Scientific Data
نویسندگان
چکیده
In this work we describe a high-performance stream-oriented distributed database manager and query processor under development that allows efficient execution of database queries to streamed data involving numerical and other data. Very high performance is attained by utilizing many object-relational main-memory database engines running on PCs and connected through the GRID.

متن کاملA Stream Database Server for Sensor Applications
We present a framework for stream data processing that incorporates a stream database server as a fundamental component. The server operates as the stream control interface between arrays of distributed data stream sources and end-user clients that access and analyze the streams. The underlying framework provides novel stream management and query processing mechanisms to support the online acqu...

متن کاملTribeca: A Stream Database Manager for Network Traffic Analysis
High speed computer and telephone networks carry large amounts of data and signalling traffic. The engineers who build and maintain these networks use a combination of hardware and software tools to monitor the stream of network traffic. Some of these tools operate directly on the live network; others record data on magnetic tape for later offline analysis by software. Most analysis tasks requi...
