2. May 2, 2003Phil Bernstein2 Drivers of Research Topics 1.Exploit Improved System Technology  networks (dist’d DB), WWW (data integration), disks (VLDBs), sensors (streaming queries) 2.New Ideas for Classical DB Technologies  access methods, query optimiz’n, auto-admin, metadata 3.Grand Challenges  Info Utility (Asilomar’98), Jim Gray’s list, CRA GC Conf no medical errors (Lomet), no auto fatalities (Lampson) 4.Combine DB & Non-DB technology  natural language, rules, data mining, XML 5.Applications  engineering, multimedia, bio-medical informatics

3. May 2, 2003Phil Bernstein3 Knowledge-Based Systems that Work ► Move from data mgmt to knowledge mgmt  A useful way to soak up desktop cycles  A big functionality improvement over DBMSs ► More logical inferencing  Theorem proving, fuzzy inferencing, model checking  Integrated with query processing and IR ► Richer knowledge representation  And much larger knowledge bases ► Engineer the combination of AI + DB  Robust systems with predictable capability ► Applications – scientific investigation, engineering design, medical diagnosis

4. May 2, 2003Phil Bernstein4 Experiment Management Systems ► Data mgmt for experimental investigation  Rapid evolution of system under test, schemas, analysis scripts, workflow  Comprehensive versioning (types, schemas, data)  Heavy use of rich data types  Heavy use of data mining  Integration with portal management ► Applications  Science – especially bio-medical  Engineering – benchmarking, process engineering
