Records and occurrences

There is an important distinction between records and occurrences.

A record is an entry in the database.

An occurrence is a record displayed in a session. An occurrence can be viewed as a slot that may contain a record.

A session can show several occurrences, in other words show several records. Not all occurrences are necessarily filled, even if more records exist in the database. Which records are displayed is affected by many factors, including sort order, filter, and user actions such as scrolling.

BFlow operates by default on occurrence one (1).

Note: A record that is displayed in occurrence five, can be moved up by the user, through scrolling, and end up in the first occurrence. Its position may also be affected by insert or delete actions on the table.

We recommend that you use the default occurrence number. The Find action returns the requested record in this first occurrence, if it exists.
