Frequently asked questions

  • How is Couchbase different from other leading databases?

    While depending on the database, customers typically come to Couchbase for four common reasons.
    • Performance: Their current databases are failing in the areas of throughput, latency, and high availability. Often it is not just one thing, but the overall architecture.
    • Flexibility: Their databases are rigid and do not support rapid application development.
    • Mobile: They want a robust, proven offline-first product. Couchbase Mobile launched in 2014.
    • Lower TCO: Their databases don’t scale to meet demands without add-on technologies and/or huge costs.

  • Is Couchbase the same as CouchDB?

    Couchbase delivers superior performance, data consistency, query capabilities, and development tools, while also offering Capella, our Database-as-a-Service. Find out more here.

  • How is Couchbase architected?

    Couchbase is a highly available distributed database that performs operations in-memory. Data is stored in JSON and queried via SQL++ or KV. The architecture includes a distributed cache and multi-model services for full-text, vector, analytics, with synchronization to mobile/edge devices via Couchbase Lite.

  • What is Couchbase used for?

    Couchbase is used by companies across all industries and a variety of operational use cases. Common cases include caching to speed of legacy applications, user profile management/personalization, dynamic product catalogs, customer 360, offline-first mobile/IoT apps, AI agents, and operational analytics. For more customer use cases, see customer stories.

  • Is Couchbase a relational database?

    Couchbase is a NoSQL database, but it does use SQL++ as the query language. The Couchbase data model, based on JSON, provides a flexible schema that can evolve by applications over time. Documents often represent a single instance of an object in application code. A document can be considered equivalent to a row in a relational table; with each of the document’s attributes being equivalent to a column. Couchbase provides greater flexibility than an RDBMS in that it can store JSON documents with varied schemas. Developers can express many-to-many relationships without requiring a reference or junction table. Documents can refer to each other by key. Couchbase does contain dynamic data structures that can be modeled to align to a relational data schema making migration easier. Learn more on data modeling.
