Does Screena provide versioning capabilities?

Yes, every version of a watchlist record is kept in memory and corresponds to a revision numeric value. In addition to the revision value, every record is tagged with its creation date/time and updated date/time. Consequently, you can access any event affecting a record including:

  • the current revision (i.e. most recent published version),

  • any corrections or enhancements, and

  • any other changes made to the record in question.

The first version of a record is always numbered as revision number 1.

We also keep in memory the date/time when a record was last matched to manage deltas as needed for periodic screening.
