A key point about the use of ENFORM in this environment is that it has the potential
to provide a snapshot of a consistent database: a database that is being changed by
transactions that modify the data. The information you retrieve will be up-to-date and
reflect the most recent changes to the data. So, reports produced by using ENFORM—
either as the result of a simple inquiry, or as one of the standard application reports—
can be based on all changes occurring to the database.
