MongoDB is a popular database that works without imposing any kind of schema. The data is stored in a JSON-like format and can contain different kinds of structures. For example, in the same collection we can have the next two documents:
JSON
xxxxxxxxxx
1
17
1
{
2
id: '4'
3
name: 'Mark'
4
age: '21'
5
addresses : [
6
{ street: '123 Church St', city: 'Miami', cc: 'USA' },
7
{ street: '123 Mary Av', city: 'Los Angeles', cc: 'USA' }
8
]
9
}
10
11
12
{
13
id: '15'
14
name: 'Robin'
15
department: 'New Business'
16
example: 'robin@example.com'
17
}
