The Collecting_Event_ID is a unique number generated by the Oracle server. The three text fields allow the data on a label to be transcribed verbatim into a table of the database.

The Collecting Event is a unique combination of time, place, method, and collectors. The Virgin Island Beetle Fauna database goes a couple of steps further, defining it as a unique combination of time, place, method, microhabitat, and collector. Each collecting unit (specimen, etc.) is collected from one and only one collecting event. There is a field for Collecting_Event_ID in the Collecting_Unit table allowing you to associate the two tables.
