What is the most mature open source database system for using Windows?

Question

After using relational databases as a backup storage for all of my Windows life cycles (currently .NET), I want to experiment with a document-oriented database this Wikipedia definition ; it can be autonomous or multi-level according to the existing non-commercial database system.

Which open-source document solution would you recommend from your own experience in Windows programming, and why? (The reason for open-source is to keep it cheap, also because open source is often pretty darn good at the forefront.)

It's nice to have a .NET provider to communicate.

Ultimately, the selected system can be turned into a real solution, if all goes well.

Admittedly, this is somewhat subjective and potentially reasoned, so keep it with real people and I will do the same - also your answers will be invaluable to others who are first accessing document-oriented databases on Windows. I am sure that the overall value of your answers outweighs any bias.

Thanks.

Answer 1

I am working on a C # mongodb driver at http://github.com/samus/mongodb-csharp/ . I really like working with MongoDB because it has some functions from the relational engine, such as dynamic queries and indexes, which makes it easy to switch to other competitors (CouchDB, RavenDB, etc.)

The MongoDB-CSharp driver has excellent Linq support for easy migration. Here you can see some of the documents not yet completed → http://wiki.github.com/craiggwilson/mongodb-csharp/ .

RavenDB Ayende is probably the most mature Windows product because it is the only (which I know) that is actually written in .net and "just works" under Windows.

Again, it is only available if you use it in open source projects. If you use it in projects with closed source, you will need to purchase a commercial license (see. On licensing information ).
Since you want to open source because it is cheap, I do not know if you are interested then.

There is more information about this on the Ayende blog .
