RavenDBs

RavenDBs refer to instances of RavenDB, a document-oriented NoSQL database designed for high performance and developer productivity. RavenDB is developed by Hibernating Rhinos and is available as a server deployment as well as an embedded option for application-local storage.

Data model: RavenDB stores data as JSON documents and supports dynamic indexing, Map/Reduce workflows, and a dedicated Raven Query Language (RQL) alongside LINQ for .NET environments. It includes built-in full-text search through its indexes and supports attachments, time-series data, and counters for specialized data patterns.

Architecture and replication: RavenDB offers a distributed architecture with automatic sharding, replication, and multi-datacenter deployments. It provides per-document ACID transactions and uses optimistic concurrency control to handle conflicts. Clusters coordinate writes and maintain data consistency, while monitoring and administration are facilitated by RavenDB Studio, a web-based management interface.

Management and security: RavenDB Studio provides a centralized UI for database management, monitoring, and maintenance. RavenDB Cloud offers a managed service option for deployments. Security features include authentication, authorization, encryption at rest, and encryption in transit, helping to protect data across environments.

Ecosystem and use cases: Official client libraries exist for multiple languages, including .NET, Java, and JavaScript, enabling integration with a variety of stacks. RavenDBs are commonly used for content management, product catalogs, user profiles, event data, and other scenarios that benefit from a flexible schema, built-in indexing, and real-time query capabilities.
