Hello Ashraf,
in CouchDB doesn't exist the concept of table or entity, as you can find in the
entity relational model. Everything is a document in CouchDB, that means both
student and message are documents. Here you have two different document types:
student and message. So, in your model, you have to add a new property called
'type' to distinguish between a student and a message.
You don't need to GET the student, you just need to store a new document to
save your message for him.
Here the student document structure:
_id
_rev
type: 'student'
name
age
Here the message document structure:
_id
_rev
type: 'message'
senderId
recipientId
title
body
I think you can understand the meaning of each property yourself.
