RavenDB is an Open Source (with a commercial option) document database for the .NET platform. RavenDB offers a flexible data model designed to fit the needs of real world systems. RavenDB stores schema-less JSON documents, and allows you to define indexes using Linq queries and focus on low latency and high performance.

  • Scalable infrastructure: RavenDB builds on top of existing, proven and scalable infrastructure.
  • Simple Windows configuration: RavenDB is simple to setup and run on windows as either a service or IIS7 website.
  • Transactional: RavenDB supports System.Transaction with ACID transactions. If you put data in it, that data is going to stay there.
  • Map/Reduce: Easily define map/reduce indexes with Linq queries.
  • .NET Client API: RavenDB comes with a fully functional .NET client API which implements Unit of Work and much more.
  • RESTful: RavenDB is built around a RESTful API.
  • Ad-hoc queries: RavenDB supports ad-hoc queries and automatically creates indexes on the fly - no need to write indexes upfront.

RavenDB is released under a dual Open Source license and a commercial license. Simply put, that means that it is freely available under the AGPL license but if you want to use this with proprietary software, you must buy a commercial license.
