Hi,

How can I avoid circular references between the classes for my database objects? I have a class "Map" and a class "Layer" referring to two tables "map" and "layer". The tables have a many-to-one relationship (many layers to one map). To create the relationship and use the dbo::collection and dbo::ptr types I should include "Map.h" in "Layer.h" and "Layer.h" in "Map.h". Obviously that causes a problem when compiling. On the other hand I don't want put all classes into one file. Could you provide me with a hint please on how to deal with this issue!?

Many thanks!
