The Image Stack Stream Model, Querying, and Architecture

Rising volumes of multimedia are being gathered with the increasing deployment of sensors. We present the Image Stack stream model/view of data for querying and visualizing the streaming data. This view is independent of the presence of a DBMS, since more sensors will capture data on a real-time basis. We outline requirements for modeling and visualizing streaming multimedia data with motivating queries. We present the Image Stack data model, a high-level query language for the model, and a system architecture and design to support these requirements. We provide highlights of a prototype implementation in Java and Java Data Objects, bypassing the use of a DBMS as permanent storage. 1
