Not entirely I'm afraid.

I think it helps a lot if you thing in *behaviors* rather than in *data* 
and *tables*. And then build a domain model around those behaviors.

For example if you have a model *Order* you could add a method 
*hasMoreThanOnePosition()* and you could use that within Fluid like;

<f:if condition="{order.moreThanOnePosition}">
   More than one
</f:if>
