Sir is it necessary to give id, if I have already object and want to save in schema instead of I'd I can give entire object,to it, then it will find it self I'd,

[@coderdost]

Yes, you can do that also. and it is a perfect solution in MongoDB. You need to understand, when it is good to have ID and when the entire object : 1. Complete Object is suitable -> If the property is unique for that parent document and changes very less. Example - if data is like your home address object. no need to save its ID - save the complete object. as that object will always be your personal address. and if it changes only needs to be changed in your document. 2. ID is good -> If the property is shared between many objects and keeps changing. For example - if that data object is your "Favorite Sports player's record" It will be better to store only ID. As that player can be the favorite of 100 other users. Also, the record will keep changing - you can't update the player record for all users in DB every time. So have the player in a separate document and then update it once, it will be changed for all users (as they are linked by ID).
