12. ADMT Lab / University of PittsburghJuly 8, 2008 Data Acquisition Data Stream Processing Web Data Management Data Dissemination

13. ADMT Lab / University of PittsburghJuly 8, 2008 Data Stream Management Systems Alerting/Monitoring Service –Register query (filter) ahead of time –“Match” against incoming data stream –Generate “events” & notify users Examples: –Stock market monitoring –Transient alerts –Google alerts –Detection of outbreak of diseases

14. ADMT Lab / University of PittsburghJuly 8, 2008 Efficient Query Scheduling (Results) Avg. Response Time (  Sec) 65% 73%

15. ADMT Lab / University of PittsburghJuly 8, 2008 User-centric Web-data Management Given an option, would you prefer slightly- stale results fast OR fresh results, slightly delayed? 4:26 AM ET

16. ADMT Lab / University of PittsburghJuly 8, 2008 How to capture user preferences? Proposed Quality Contracts Framework Micro-economic paradigm Combination of quality functions Consider Quality of Service (response time) Consider Quality of Data (freshness) Basic idea: Convert performance on individual metric into “worth” to users Use Quality Contracts to guide resource allocation

18. ADMT Lab / University of PittsburghJuly 8, 2008 Scientific Data Management Biological Data Management Center for Modeling Pulmonary Immunity –NIH-funded (2005 - 2009) –4 centers in the US –Build mathematical models of immune response –http://cmpi.cs.pitt.eduhttp://cmpi.cs.pitt.edu Data exchange server –Platform to record all experimental information –Enable sharing & interoperability across centers

19. ADMT Lab / University of PittsburghJuly 8, 2008 Data Exchange Server Platform to exchange experimental data –Goal 1: organize data already online –Goal 2: capture data from notebooks –Goal 3: allow for new data to be recorded Provenance (data lineage) Annotations –Goal 4: export / import capability –Goal 5: make repository user-friendly –Goal 6: minimize need for data cleaning –Goal 7: make repository active (alerts) Publish / Subscribe
