  1. Mobile Data Management Ken Rimey 1.6.2004

  2. Mobile Data Management • How can people store, organize, identify, locate, maintain, and safeguard their data on all their various electronic devices? • Formulating a unique vision: • Personal devices, • Device-to-device communication, • Small, collaborative user groups, • Publish / Consume Collaborate, • Distributed XML database as technology core.

  3. People • Individuals may own many devices. • They collaborate within social groups: • Family • Friends • Coworkers • They engage in various external relationships: • Service providers • Internet communities • Strangers

  4. Data What applications should we experiment with? • Digital media? • Documents? • Personal databases (PIM)? • Device and device group configuration? • Context data? • (Maybe identifying the next killer app should not be our goal.)

  5. Devices Broad interoperability: • Handheld devices • Home and car electronics • Personal computers • Large-scale servers • Sensors

  6. Drivers • Ultrawideband local wireless networks? • Exploding capacity of portable storage? • The software problem? • Social trends?

  7. Projects Two possibilities so far: Too Many Boxes – How will ordinary people manage their data? XML – Design issues in distributed XML databases for mobile devices. Too Many Boxes Utilization: DistributedXML database XML Implementation:

  8. Too Many Boxes • End-user management of replicated data on personal devices: • Organizing and finding data. • Aggregating data for management purposes. • Controlling which devices store replicas. • Controlling automatic data synchronization. • Controlling access by other devices and people. • Combine architectural prototyping with user testing in order to develop a design that is powerful and yet easy to understand.

  9. XML • Distributed XML databases for mobile devices. • Consortium project between HIIT and HUT. • Key research issues: • Local aspect: • Appropriate technology for small devices. • Automatic index creation based on observed queries. • Network aspect open for discussion: • XML in cellular network. • XML in wireless local area networks.
