Flexible Data Model

With Couchbase Server, you use JSON documents to represent application objects and the relationships between objects. This document model is flexible enough so that you can change application objects without having to migrate the database schema, or plan for significant application downtime. Even the same type of object in your application can have a different data structures. For instance, you can initially represent a user name as a single document field. You can later structure a user document so that the first name and last name are separate fields in the JSON document without any downtime, and without having to update all user documents in the system.

The other advantage in a flexible, document-based data model is that it is well suited to representing real-world items and how you want to represent them. JSON documents support nested structures, as well as field representing relationships between items which enable you to realistically represent objects in your application.
