11 ADMT Lab / University of PittsburghJuly 8, 2008 Graduate Students Lory Al Moakar Roxana Gheorgiou Shenoda Guirguis Qinglan Li Panickos Neophytou Jie Xu Staff: Alex Connor Advanced Data Management Technologies Lab Department of Computer Science, University of Pittsburgh Stream Data Management Web & Real-time Data Management Scientific Data Management Sensor Data Management Mobile Data Management People Research Panos Chrysanthis Alex Labrinidis User-centric Data Management for Scalable Network Centric Applications

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

17 ADMT Lab / University of PittsburghJuly 8, 2008 Center for Modeling Pulmonary Immunity +=

18 ADMT Lab / University of PittsburghJuly 8, 2008 Scientific Data Management Biological Data Management Center for Modeling Pulmonary Immunity –NIH-funded ( ) –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

20 ADMT Lab / University of PittsburghJuly 8, 2008 Advanced Data Management Technologies Lab Department of Computer Science, University of Pittsburgh Stream Data Management –Efficient Query Scheduling –AQSIOS project Web & Real-time Data Management –Quality Contracts –Admission Control –Transaction Scheduling Biological Data Management –Data Exchange Server –Annotation (Metadata) Management –Publish/subscribe Sensor Data Management Mobile Data Management Directors Panos Chrysanthis Alex Labrinidis Research User-centric Data Management for Network Centric Applications
