I have introduced the Persistent Data Services (persistentdata) package APIs over the last five weeks.

Persistent Storage collection

  • Central Repository, the settings store
  • DBMS, the first database engine for Symbian
  • Symbian SQL, the client-server database incorporating SQLite
  • SQLite3 API, the standard SQLite C API
  • Store, the essential classes for data persistence

Logging Services

  • Event Logger, the database of recent calls and other events
  • File Logger, a file logger for debugging purposes
  • RFile Logger, the file logger for Test Execute Framework

Feature Management

  • Feature Manager, the API to query the presence or absence of hardware and software features
  • Feature Registry, a deprecated API to query feature status

Trace Services

  • Comms Debug Utility, a file and serial port logger for debugging purposes
  • Trace Framework, the trace API replaced by Open System Trace framework
  • UTrace, a deprecated trace API

Links to each post in the series are available in the first post in the series.

What did you think about the series? What do you want to know more about? What was most or least useful?

Please leave a comment to share your opinion.

    I thought it was great! I certainly know a lot more about your package than I did before.

    I would like to see posts about how persistentdata is used by other packages. This would serve as good examples for app developers.

    Thanks for your feedback. I’m glad you found the series useful.

    I like your idea to describe how other packages use persistentdata. I will try to follow-up on this suggestion in the months ahead.
