MongoDB Database - mongodb

Question

well... I don't know anything about not relational data base and I wanna know if the following script is correct.
The data base it's developed for obtain management of users and schedules, (The schedules are related with a professor and a classroom). The classrooms have a code and they can be commented and rated by users.
db.user.insert({
//Can be 6 o 10 digits
_id : 201309,
name : {
First : "Fernando",
Last : "Sarmiento"
},
area : 2,
account : {
email : "email#google.com",
password : "Password1!",
level : 0
},
status : {
status : "Active",
Date : 17-01-2016
},
//Can be null
comment : "I like cereal",
})
-
db.schedule.insert({
_id: ObjectId(),
day : "Lunes",
hour : 13 : 00,
finalHour : 14 : 00,
teacher : {
$ref : "user",
$id : $id.user
},
classroom : {
$ref : "classroom",
$id : $id.classrom
}
})
-
db.classroom.insert({
_id : ObjectId(),
name : "Software Development",
comment : "classrom 3",
//Can take values from 0 to 5
score : $avg(userScore),
code : [
{
code : "ABCDEF123456",
user : [{
$ref : "user",
$id : $id.user
}]
}
],
post : [
{
post : "I like the classrom :)",
date : 17-01-2016,
user : [{
$ref : "user",
$id : $id.user
}]
}
],
userScore : [{
score : 4.5,
user : [{
$ref : "user",
$id : $id.user
}]
}]
})
Thanks! :3
