What is the best way to set up a relationship between two tables where
table-1 has a one-to-one relationship with table-2 but table-2 has a
one-to-many relationship with table-1?
For example, suppose there is an events application (seminars, forums,
conferences, etc). Each event has only one address but since many
events can occur at the same location throughout the year, a given
address can belong to many events.
