I have one name in the people table who owns 5 different dairies with three
different phone numbers, but all 5 have the the same email address.
The five dairies each has its own name and location while the people table
has five rows with the same last and first names and email address.
Is there a way to have only one entry for the owner in the people table
while related to five different company names? In some industries, such as
dairy farms, this is not an unusual situation.
Read up on “many-to-many” data models. In SQL they involve a linking table, one row per bidirectional edge, in addition to the two node tables.
