UltraLite User's Guide
Developing UltraLite Applications
Designing your UltraLite database
Some UltraLite applications require client-specific data that control synchronization, but which are not needed on the consolidated database. For example, you may wish your UltraLite applications to indicate which of a number of channels or topics they are interested in, and use this information to download the appropriate rows.
If you create a table in your UltraLite database with a name ending in allsync, all rows of that table are synchronized at each synchronization, whether or not they have been changed since the last synchronization.
You can store user-specific or client-specific data in allsync tables. If you upload the data in the table to a temporary table in the consolidated database on synchronization, you can use the data to control synchronization by your other scripts without having to be maintained in the consolidated database.
