"Hibernate" for Mono and .NET

Similar to the technologies Hibernate, NHibernate, and LINQ, the Mono platform allows similar technology for working with databases in a object-oriented manner.

The name of the technology is DB4O, and information on it may be found here:

http://www.mono-project.com/DB4O

The organization that maintains DB4O is:

http://www.db4o.com/?src=Mono

At the first link, there is a C# example of working with databases and DB4O, as follows:

using System;

using Db4objects.Db4o;

public class Test {

  static string _file = "store.db4o";

  // A very basic db4o example that demonstrates
  // automatic schema generation and Query-By-Example
  public static void Main (string [] args)
  {
      using (IObjectContainer db = Db4oFactory.OpenFile (_file)) {
          db.Set (new Pilot ("Michael Schumacher", 101));
          db.Set (new Pilot ("Rubens Barrichello", 99));
          db.Commit ();

          IObjectSet pilots = db.Get (new Pilot(null, 101));
          foreach (Pilot p in pilots) {
              Console.WriteLine (p);
          }
      }
  }
}

public class Pilot {

  string _name;
  int _points;

  public Pilot (string name, int points)
  {
      _name = name;
      _points = points;
  }

  public override string ToString ()
  {
      return _name + "/" + _points;
  }
}

Another option, based on LINQ, can be found at: http://siaqodb.com/

Siaqodb appears to be very interesting too, another option for avoiding direct SQL management.

Enjoy it!
