I have to save this information in a database
Person -> is married to -> Person
Where should I save that information? What is the proper design pattern should I apply here?
Thank you!
If you can only be maried to one person: 1:1
-------------
- Person -
-------------
id (key)
maried_to_id (foreign key)
If you can be maried to more than one person or want to keep track of previous mariages, n:n
-------------
- Person -
-------------
person_id (key)
-------------
- Mariage -
-------------
first_person_id (foreign key)
second_person_id (foreign key)
start_date
end_date
(also first_person_id + second_person_id + date form a unique key for mariage. You could leave out the date, but then remariages wouldnt be tracked)
