  7. Data synchronisation • Efficiency: changes are done one time • Quality: less mistakes • Security: less pollution of data • Clearity: when it’s clear who is the owner, it is clear who is responsible

  8. Data synchronisation Concepts • Db connection • Difficult to make • Permission/support • Update • Event driven is possible • API interface • Difficult to make • Event driven is possible • Text-based export/import • Easy • Security • Only batch processing

  9. Snapshot Concepts • Records are created or changed with an “identifier”: Data-source-key • Fields can be defined as: • Blackboard owned: when changed with Bb UI, snapshot does not overwrite • Snapshot Owned: when changed with Bb UI, snapshot does overwrite

  10. Features • Input has three variations: • Snaphot: all data in input file + DCK will be processed. Data in Bb with the same DCK which is not in the input file will be disabled. • Manual: all data in input file + DCK will be processed. Data in Bb with the same DCK which is not in the input file will stay the same • Remove: all data in the input file + DCK will be removed

  11. Snapshot components • Snapshot generator: • Custom build software to generate input files • Snapshot tool: • set of commands, to be executed at the command prompt, to change a large number of records using an import file. • Snapshot controller: • Determines input files • Checks validation of data • Import input files, using the appropriate snapshot commands and data source key’s • Generates log files

  12. Snapshot programs

  13. USER Maintenance • Users.txt Bold = bb-owned

  14. Course and Organization Maintenance • 0405_courses.txt • 0405_org.txt Bold = bb-owned

  15. Enrolment and staff assignments • 0405_enroll.txt • 0405_orgmemb.txt • 0405_staff.txt Bold = bb-owned

  16. Catalogue • Category.txt • Manage course and organization catalogue structure • Links.txt • Links course/organization in the appropriate place in catalogue structure

  17. Monitoring • Controller.log • Bb-services-log-snapshot-jdbc.txt

  18. Monitoring II • Copy the input files to a webserver where they can by monitored by key users of Bb: LINK www.unimaas.nl - /eleum/logfiles/ [To Parent Directory]Tuesday, October 05, 2004 6:00 AM 221312 0405_COURSES.TZATuesday, October 05, 2004 6:00 AM 2018976 0405_ENROLL.TZATuesday, October 05, 2004 7:01 AM 22620 0405_ENROLL.TZA.invalidTuesday, October 05, 2004 6:00 AM 57199 0405_LINKS.TZATuesday, October 05, 2004 6:00 AM 597822 0405_ORG.TZATuesday, October 05, 2004 6:00 AM 1361296 0405_ORGMEMB.TZATuesday, October 05, 2004 7:04 AM 14952 0405_ORGMEMB.TZA.invalidTuesday, October 05, 2004 6:00 AM 105824 0405_STAFF.TZATuesday, October 05, 2004 7:02 AM 4539 0405_STAFF.TZA.invalidTuesday, October 05, 2004 6:00 AM 16842 CATEGORIES.TZATuesday, October 05, 2004 7:04 AM 6750 controller.logTuesday, October 05, 2004 6:30 AM 2453086 USERS.TXTTuesday, October 05, 2004 6:44 AM 6552 USERS.TXT.invalid

  19. Steps • Make an inventory of fields needed for maintenance of • Users • Courses • Organizations • Enrolments in courses and organizations • Staff assignments • Determine syntax (Course-id’s, course-names etc) • Determine source for data needed • Determine snapshot or Blackboard ownership • Determine data source key’s • Write snaphot generator application • Create course and organization templates

  20. Input • Documentation • Blackboard consultancy

  21. Missing features • Additional Administrative role: • View all courses • View all organizations • View all enrolments in courses and organizations • View all staff assignments • View users • Cannot change anything This would make it a lot easier for educational offices to analyze problems in Bb and correct them in the SIS. • Maintenance of group pages
