Stanford: Stream data manager

http://www-db.stanford.edu/stream/index.html

In applications such as network monitoring, telecommunications data management, web personalization, manufacturing, sensor networks, and others, data takes the form of continuous data streams rather than finite stored data sets, and clients require long-running continuous queries as opposed to one-time queries. Traditional database systems and data processing algorithms are ill-equipped to handle complex and numerous continuous queries over data streams, and many aspects of data management and processing need to be reconsidered in their presence. In the STREAM project, we are reinvestigating data management and query processing in the presence of multiple, continuous, rapid, time-varying data streams. We are attacking problems ranging from basic theory results to algorithms to implementing a comprehensive prototype data stream management system.
