N1QL ("SQL for JSON")
N1QL (pronounced “nickel”) is Couchbase’s next-generation query language. N1QL aims to meet the query needs of distributed document-oriented databases. The N1QL data model derives its name from the non-first normal form, which is a superset and generalization of the relational first normal form (1NF). In Couchbase, we use N1QL for querying the data present in a Couchbase data bucket.
