Relationship between two documents in MongoDB - NodeJS || Hindi #92
/ codingscenes
In MongoDB, you can manage relationships between documents using two main approaches: embedding and referencing. Let me explain each of them with examples.
Embedding:
In this approach, you can directly embed related data within a document. This is useful when the related data is small and doesn't change frequently.
Referencing:
In this approach, you store references to related documents using their unique identifiers (IDs). This is useful when the related data is large or frequently updated.
Let's continue with the blogging application example. Instead of embedding the posts within the user document, you can create a separate "posts" collection and store references to the associated user in each post document.
