Final answer:
It is false that Field History is not recorded until the end of a trigger event; field updates are recorded immediately after they are committed during the trigger execution.
Step-by-step explanation:
The statement that Field History is not recorded until the end of a trigger event is false. In the context of database systems, especially those that are part of Customer Relationship Management (CRM) platforms such as Salesforce, field history is actually recorded as soon as the field is updated and the transaction is committed, which can occur at various points during the trigger execution, depending on when the update is performed and committed within the trigger's logic. However, the field history might not be immediately visible or reportable until the end of the trigger event due to transactional consistency.
