The need of a data stream management system (DSMS), with the capability of querying continuous data streams, has been well understood by the database research community. We provide an overview on a DSMS prototype called T2. T2 inherits some of the concepts of an early prototype, Tribeca [M. Sullivan et al. (1998)], developed also at Telcordia, but with complete new design and implementation in Java with an SQL-like query language. Our goal is to build a framework that provides a programming infrastructure as well as useful operators to support stream processing in different applications. We set our first targeted application to healthcare biosensor networks, where we applied T2 to monitoring and analyzing electrocardiogram (ECG) data streams, arriving via wireless networks from mobile subjects wearing ECG sensors. Monitoring remote patients via wireless sensors not only provides convenience and safety assurance to the patients, but also saves health care cost in many aspects.
