JSONiq - The SQL of NoSQL
5 likes4,993 views
The document discusses JSONiq, a declarative query language for JSON that serves as a standardized approach for NoSQL databases, specifically highlighting its features such as composability and native support for JSON. It covers key aspects like scalability, high availability, sharding, and rich data models in NoSQL environments, showcasing contributions from organizations like 28msec and Oracle. Additionally, it lists various implementations and drivers that support JSONiq, including MongoDB and CouchDB.
