I need help to decide what way follow in order to modeling this data in mongodb -



I need help to decide what way follow in order to modeling this data in mongodb -

i have 3 entities, , inheritance following:

countries | - provinces | - cities

in denormalized (or embedded) construction following:

one illustration document countriescollection

{ name : "argentina", provinces : [ { name : "santa fe", cities : [ { name : "rosario", zipcode : 2000 }, { name : "other", zipcode : 3142 }, ... ] }, ... ] }

what going take city zipcode field (which going unique) , assign person document in order identify city. pain query cities structure, when want filter cities in search box.

the other thought (based on going work cities in mostly) separate entities collections , link every city document province 1 using province_id field (just saying).

what want not duplicate information. in case?

cheers!

mongodb
