Abstract
This paper describes our ongoing work developing the Stanford Stream
Data Manager (STREAM), a system for executing continuous queries over
multiple continuous data streams. The STREAM system supports a
declarative query language, and it copes with high data rates and query
workloads by providing approximate answers when resources are limited.
This paper describes specific contributions made so far and enumerates
our next steps in developing a general-purpose Data Stream Management
System.
