Streaming Data

• Jianjun Chen, David J. DeWitt, Feng Tian, Yuan Wang. NiagaraCQ: A Scalable Continuous Query System for Internet Databases. Proc. SIGMOD Conference, 2000, 379-390. We are reading this paper because it's a good example of a system for answering queries that are updated continuously - a precursor of streaming systems. You may skip sections 3.4 and 3.5, and skim section 5, but you should read the rest of the paper. Note that the reason that the paper used XML-QL rather than XQuery (the current standard) as a query language is that XQuery did not exist at the time. However, many features of XQuery are based on XML-QL.

Monitoring Streams - A New Class of Data Management Applications. Proc. VLDB, 2002, 215-226. We're reading this paper because it's a good example of a later project on streaming data.
