Transcription de la présentation

  1. Introduction to Information Systems Debriefing Project Phase 1

  2. The Project – Side Effects • Trains your soft skills • team work • deal with bugs, poor documentation, … • produce with limited time resources • project management and reporting • Results useful for you personally • Demo: • Project should be fun 

  3. Debriefing • First: work done is impressive!

  4. Bugs and Company • As expected real life is full of surprises • problem with 5MB limit • problem with Ebay • difficulties with SED • bugs in Pointbase • syntactic variations in Pointbase • …

  5. An Imperfect World • The data is not always of the quality you expect it to be (sometimes on purpose?) • more in this follows for Phase 2 • Conceptual Schemas • Redesigns (not a "problem with 'us'" ;-) ) • "Agreement" on schema • Some data didn't fit (trees) • Regular expressions are sensitive to changes

  6. Time Management • First phase was (not unexpectedly) very time consuming • Phase 2 and 3 should be better • Tradeoff between doing something "real" and saving time • Some groups reported on insufficient planning • Specialists in group for different tasks

  7. The practical side • Some adaptations for phase 2 • you will find more assistants on Friday • Password protection if desired • Experience report in PDF format • deliverable as ZIP file by email • Roman will have more information • Please use the News Group for Questions!

  8. Suggestions for Phase 2

  9. Database Integration • Combining data from different databases • collection of data (wrapping) • combination of data and generation of new views on the data (mediation) • Problem: heterogeneity • access, representation, content • Example revisited (Demo) • http://immo.search.ch/ • http://www.swissimmo.ch

  10. Suggestions for Phase 2 • When integrating data • no "perfect" database expected: output cannot be better as input! • partial matches from DBs are ok • data quality has no influence on grading!

  11. Suggestions for Phase 2 • Important • integration at schema level • observe and report the difficulties • planned: debriefing on database integration problems

  12. So • Good luck • and watch the time
