2. 2 Project Topics in a Nutshell:  Distributed Data Sources:  EVE : Data Warehousing over Distributed Data Sources  TOTAL-ETL : Distributed Extract Transform Load Tools  Web Information Systems:  RAINBOW : XML to Relational Database Management  MASS : Native XQuery Processing System  Databases and Visualization:  Visualization-Driven Data Caching  Prefetching based on User Access Patterns  Stream Monitoring Systems:  Querying of Data Streams  Monitoring Applications

3. 3 CAPE : Engine for Querying and Monitoring Streaming Data Example of Stream Data Applications: Market Analysis –Streams of Stock Exchange Data Critical Care –Streams of Vital Sign Measurements Physical Plant Monitoring –Streams of Environmental Readings

4. 4 Databases Upside Down Databases Upside Down data Query data streams of data static data Standing queries one-time queries

5. 5 MQP Projects in CAPE  Work on core engine, such as query processor, scheduler, query approximator, data shedder, distributer, resource allocator, etc.  Develop full example application, e.g.: TRAFFIC,  Load real data streams : traffic simulation  Develop useful queries, like “average density in city region X over last 5 minute window”  Provide GUI to specify query, eg. By drawing a rectangle over city map.  Supply visual results to traffic monitor, e.g., in charts of time trends.
