RavenDB is a document-oriented database designed for applications that need flexible data structures without sacrificing transactional consistency. It stores information as documents and provides an integrated set of tools for querying, indexing, replication and database administration.
RavenDB supports ACID transactions and can coordinate changes across multiple documents. This is particularly useful for business applications where related updates must succeed or fail together.
Its query language, RQL, uses SQL-like syntax adapted to document-oriented operations. Applications can work with nested objects, retrieve related documents and execute complex queries without relying on conventional relational tables.
One of RavenDB’s distinctive features is automatic indexing. The database can create indexes in response to application queries and maintain them as the underlying documents change. Developers can also define custom indexes for workloads requiring greater control.
RavenDB provides a browser-based management studio for inspecting documents, running queries and monitoring database activity. Its transaction and indexing capabilities make it suitable for substantial server-side applications.
This is free and open source software.
