Scopes and Collections is a powerful feature in Couchbase that enables developers to isolate data logically, promoting independent app lifecycle management and enhancing efficient, scalable, highly secure handling of data for distributed mobile and edge applications. This feature supports Capella App Services, including Couchbase Lite, allowing for fully managed mobile and IoT app deployments on Capella as well as self-managed deployments. Scopes and Collections provide an elegant way to categorize and organize documents within a Couchbase bucket, enabling access and security at varying levels of granularity. By leveraging Scopes and Collections in App Services, developers can simplify migrations from relational databases, support scalable multi-tenant applications, and enable high application density at the edge, ultimately improving data management and scalability for distributed mobile and edge applications.
