What is a dcoument in NoSQL database?

A document in MongoDB is equivalent to a row in a table in RDBMS. Documents are stored in BSON format and are gathered together in collections.

  1. 1

    It is a data structure composed of field and value pairs. MongoDB documents are similar to JSON objects. The values of fields may include other documents, arrays, and arrays of documents.

  2. 2

    Documents correspond to native data types in many programming languages.

  3. 3

    Embedded documents and arrays reduce need for expensive joins.
