▪Declarative query language that extends SQL for JSON

▪SELECT, INSERT, UPDATE, DELETE, MERGE, EXPLAIN

▪Sort, filter, transform, group, and combine/join data

▪Query data via language integration

17

©2016  Couchbase  Inc.

▪JSON documents – Rich structure – Structure evolution

▪SQL – General query functionality – Query across relationships

▪Why N1QL? – Developers already know SQL – No need for complex query frameworks

Access  NoSQL  using  JDBC▪JDBC driver for accessing Couchbase ▪Run N1QL queries ▪Get JSON data through standard JDBC interfaces ▪JSON types supported

– Simple values (string, numbers, boolean, …) – Compound (objects, arrays, …)

▪Users – BI/ETL Tools (Tableau, Informatica, …) – Persistence providers (EclipseLink, Hibernate, …)
