Field is a name-value pair in a ___

15. Field is a name-value pair in a ___.

  1. Attribute
  2. Table
  3. Document
  4. None of the mentioned above

Answer: C) Document

Explanation:

A field in a document is a name-value pair that contains information. There are zero or more fields in a document. Fields in relational databases are analogous to columns in traditional databases. In MongoDB, each document stored in a collection is identified by a unique _id field, which serves as the collection's primary key. If the _id field is not present in an inserted document, the MongoDB driver creates an ObjectId for the _id field by generating it automatically.
