As NoSQL adoption grows, developers and enterprises require a general-purpose database to replatform their mission-critical applications and services. MongoDB provides a procedural method to query data, but this approach has limitations such as proprietary syntax, complexity, limited expressive power, and poor query optimization. In contrast, Couchbase adopts an open-standard SQL approach with its N1QL language, offering support for ANSI join constructs, advanced query optimization, and indexing capabilities that scale to meet the performance requirements of critical business applications.
