Linking related data in MongoDB can be achieved by using techniques such as embedding documents or referencing documents, depending on the structure and requirements of your application. Here's an overview of both approaches:
Store related data within the same document. This is useful for closely related data that is accessed together.
Fast and easy to access related data.
Reduces the need for joins or multiple queries.
Store related data in separate collections and reference them using unique identifiers
Keeps documents lightweight and scalable
Flexible for complex relationships
