Can one make a relational database using MongoDB?

Question

Can I co-relate two tables with the help of a common key in MongoDB? Basically I am designing a Student Management System with the help of MongoDB and I will have one table for students and another for attendance records. 

Answer 1

In MongoDB, there are many options available but the most basic one is to embed the attendance data into each student document. 

db.student.find( { login : "sean" } )

{

  login : "sean",

  first : "Sean", 

  last : "Hodges",

  attendance : [

    { class : "Maths", when : Date("2011-09-19T04:00:10.112Z") },

    { class : "Science", when : Date("2011-09-20T14:36:06.958Z") }

  ]

}

Using the above code it will be easier for you to retrieve the attendance data for each and every student.
