I have three collections. User, Address, and Workplace. To maintain my data easily, I have used the _id of User collection as the ids of Location and Workplace collections. For example, if I want to store a user's information, I will store it like this -

A document in User collection

{
  _id: ObjectId("605d6d93e1715f3650a8e8c2"),
  name: A
}

A document in Address collection

{
  _id: ObjectId("605d6d93e1715f3650a8e8c2"),
  address: District B
}

A document in Workplace collection

{
  _id: ObjectId("605d6d93e1715f3650a8e8c2"),
  workplace: District C
}

Is it a good idea to use the same id? If no, what problems I might face in the future? Any help would be appreciated. Thanks in advance.
