I was looking at porting a small side project over to use Mongo, as it was getting more and more time consuming using Nhibernate for the current scenario.
I gave NoRM a try originally, and that had a branch which had support from cyclic references and worked fine, however I cannot find any documentation to indicate if the official c# driver supports it.
The situation and why I have a cyclic reference is because I have a location object, which contains a list of roads, each road has a link to another location. It is quite similar to a simple set of nodes in a pathfinder.
public class Location
{
public int Id { get; set; }
public string Name { get; set; }
public IList<Road> Roads { get; set; }
}
public class Road
{
public Location From { get; set; }
public Location To { get; set; }
}
Now the problem is I have a whole world built up out of these objects (they have more properties in the real scenario) and they all interlink, however without being able to handle cyclic references I am not sure how I can solve this problem, as each road needs to know a start and an end point.
I know one compromise is to just get rid of the location object, and instead have an Id that references the location, but then I have to query each sub location individually. This is only done once and then kept in memory as there is a huge map that contains all possible locations and all possible routes so quick paths can be found between points.
It may be a case of the Location and Roads are not suitable for a document storage approach and can be stored another way...
