I heard a saying: there is an array where the database is less efficient than the present

Basically thats right but it's better to have all data in one place and if
you extend your data and relations you get into trouble soon. Think what
happens if you want to export all user data someday. In your DB you
have the digits 1,2,3,4 etc. but only looking at your sql export you don't
know what the digits stand for.

If you want to set up this dating-services I would do some research about
"DB normalization"!
