Detailed explanation-1: -An embedded, or nested, MongoDB Document is a normal document that’s nested inside another document within a MongoDB collection. Embedded documents are particularly useful when a one-to-many relationship exists between documents.
Detailed explanation-2: -To create a relationship in MongoDB, either embed a BSON document within another, or reference it from another. MongoDB databases work differently to relational databases. This is also true of relationships.
Detailed explanation-3: -In MongoDB, a relationship represents how different types of documents are logically related to each other. Relationships like one-to-one, one-to-many, etc., can be represented by using two different models: Embedded document model. Reference model.
Detailed explanation-4: -Embedded documents are an efficient and clean way to store related data, especially data that’s regularly accessed together. In general, when designing schemas for MongoDB, you should prefer embedding by default, and use references and application-side or database-side joins only when they’re worthwhile.
