Best design for entities with multiple values
Say you have an entity like a vehicle that you are capturing detailed information about. The car you want to capture is painted red, black and white. The front tires are Bridgestone 275/35-18 and the rear tires are 325/30-19. And sometimes you can have just two tires (yes this would be considered a motorcycle which is a type of vehicle) ...
Design problem regarding type slicing with many different subclasses.
A basic problem I run into quite often, but ever found a clean solution to, is one where you want to code behaviour for interaction between different objects of a common base class or interface.

Reporting with db4o
I've used db4o with much success on many projects in the past.
