​ A one-to-many relationship exists between two tables  when one record in the first table matches zero, one, or  many records in the second table, and when one record  in the second table matches at most one record in the fi rst table. Here, the Owner and Animal tables have a  one-to-many relationship because an Owner can own  many animals, and each animal is associated with only  one owner. The two tables are still separate tables, but  because they are joined, you can use the data in them  as if they were one table.

Access does not require a field description for every field included in a table.  _________________________
