I have 20 DBs (JSON Files)
I am using vuejs for frontend + nodejs & mongo for backend
I have some JSON DB store phone number as an array and another JSON DB store them as number filed
the same case with email filed some with array and some with string filed
Is there any difference in searching query for array and data filed?
Which the best case to use ( Convert data filed to an array or the opposite)?
My app focuses on reading most of the time not on an update or create or delete
