Actions are the events that the actors performed that should be audited. In the spreadsheet example application, some of the most obvious actions might include
sheet.delete. Sometimes it’s important to create new objects to wrap events. For example, if a user is editing a spreadsheet and the sheet saves every second, you don’t want to create a
sheet.update event each second. Wrap these events into a session and create a single
sheet.update event for the entire edit session.
