Couchbase 7.0 introduces Scopes and Collections, offering a new way to organize JSON data that simplifies the migration from relational databases to the Couchbase document data model. Scopes serve as logical containers analogous to schemas, while Collections function like tables, facilitating the organization and management of data. This update enhances the N1QL query language by eliminating the need for a type field in every document, making queries simpler and more intuitive, and improving JOIN conditions. The new model retains compatibility with the previous Bucket model, allowing users to transition at their own pace. Migrating involves a straightforward process of creating Scopes and Collections, ensuring unique document keys, copying data, converting indexes, and updating queries. The changes aim to streamline data handling and querying, leveraging Couchbase's distributed architecture for greater scalability and availability.
