N1QL (pronounced nickel; Non-first Normal Form Query Language or Couchbase Query Language) is a query language developed by Couchbase for finding data in document-oriented database, Couchbase Server.

The N1QL data model is non-first normal form (N1NF) with support for nested attributes and domain-oriented normalization. The N1QL data model is also a proper superset and generalization of the relational model.

Announced at Couchbase Live Europe, 23/03/15 N1QL will be renamed "SQL for Documents" under the 4.0 release [1]
