Theodore Johnson will be visiting the department from ATT Labs on
Wednesday, October 24. He'll be giving a talk about Data Stream
Warehousing.

The talk will be 12 noon to 1:30 pm, in Room 302.


Abstract:
Data stream processing is a well-studied area that has led to
many commercial offerings. Stream processing systems typically
store only a small history of a stream, and provide services
such as real-time alerting and visualization, and data
reduction for downstream processing. However many applications
also require that long term (e.g. 2 year) histories
as well as real-time data be provided to analysts. A stream
warehouse combines aspects of data stream processing (continual
data ingest) with data warehousing (long-term storage and
materialized views). I will discuss special issues and
opportunities that arise in stream warehousing, and stream
warehouse applications within AT&T Labs - Research.

Bio:
Theodore Johnson received a PhD in Computer Science from New York
University in 1990.  From 1990 through 1996, he was an Associate Professor
at the CISE department of the University of Florida.  In 1996, Ted moved to
the Database Research group of AT&T Labs - Research and has been there since.
Ted has specialized in data steam management systems, being one of the
principal authors of the GS Tool (previously, Gigascope) and of the DataDepot
stream warehouse.  Ted has written two books, Distributed Operating Systems and
Algorithms (with Randy Chow) and Exploratory Data Mining and Data Cleaning
(with Tamraparni Dasu).
