Description: Related Entities in NoSQL databases refer to documents that have a connection or relationship with each other within a database. In the context of NoSQL databases like MongoDB, entities can be represented as documents in collections, where each document can contain information about a specific object or concept. These entities can be related in various ways, such as through direct references, where one document includes the identifier of another, or through the inclusion of subdocuments, where one document nests other documents within its structure. This flexibility allows developers to model data more naturally and according to the needs of the application, facilitating the representation of complex relationships. Related entities are fundamental for maintaining data integrity and for performing efficient queries that involve multiple documents. In NoSQL databases, how these relationships are managed can influence the performance and scalability of the database, making the understanding of related entities crucial for designing effective schemas.
