Transaction and row state management

UltraLite maintains state information along with the data in the database. UltraLite tracks and stores state information so it can manage:

  • Concurrent connections, so UltraLite can share resources as required.

  • Synchronization progress state, to ensure that synchronization occurs successfully.

  • Row state, to maintain data integrity by tracking how data has changed between synchronizations.

  • Transactions, to determine when and how data gets committed. In UltraLite, a transaction is processed in its entirety or not at all.

  • Recovery and backup information, to protect data against operating system crashes, and end-user actions such as removing storage cards, or device resets while UltraLite is running.
