N1QL
N1QL (pronounced 'nickel') is a query language for Couchbase, a NoSQL document database, designed to combine the flexibility of JSON with the power of SQL-like syntax. It allows developers to query JSON documents using familiar SQL constructs, enabling complex queries, joins, and aggregations across distributed data. N1QL integrates with Couchbase's architecture to provide high performance and scalability for modern applications.
Developers should learn N1QL when working with Couchbase databases to efficiently query and manipulate JSON data in a way that bridges NoSQL and relational paradigms. It is particularly useful for applications requiring ad-hoc queries, real-time analytics, or complex data relationships, such as e-commerce platforms, content management systems, or IoT data processing, where SQL-like expressiveness is needed on unstructured or semi-structured data.
