Stream Query Repository
Introduction Application Domains


This web page contains a repository of data stream schema and queries, called the Stream Query Repository (SQR), maintained as a resource for researchers in data streams. Data stream processing is now commonplace in applications such as network monitoring, telecommunications data management, sensor networks, publish-subscribe, web personalization, manufacturing, and others. For each such application domain, we collect data and schema specifications, query specifications, and expressions of the queries in different query languages. SQR is partitioned on a per-application-domain basis. Follow the links below to access the repository of data and query specifications for each domain.
