Say Adarsh has two child ages 15 & 19 then in RDBMS we may have to create Two tables if we need data normalized
tab_person
-------------------------
Person | Name | _id |
-------------------------
1 | Adarsh | x |
--------------------------
tab_children
---------
id | Age |
---------
x | 15 |
x | 19 |
-------
In JSON we can write the above in a single Document
JSON
{
person:1,
name:"Adarsh",
ChildAges:[15,19]
}
