Capturing Entity information called from another Entity

Question

Hi All,
How do I capture information of a Entity in another Entity.
Assume we have to collect the children names, and type of toys each child have (if any)
i.e.
Properties File
Entity: Children
Relationship: 1-Many {Global - Children}
w/ Attributes:
Name {Text}
The Child has Toy(s) {Boolean}
Entity: Toy
Relationship: 1-Many {Children-Toy}
w/ Attribute:
Name of Toy {Text}
this is the rule base so far, I can see that i've not really set out the relationships correctly, could anyone please advise.
Rule Base
*The addtional toy information is gathered if*
The information on children who have toys or
The information on children who are not fortunate to have toys
*The information on children who have toys if*
For at least one of a Children, The Child has Toy(s)) and
ExistsScope(a children)
     for(a toy, name of toy is known)
*The information on children who are not fortunate to have toys if*
ForAll(a Children, Th Child has not Toy(s) ) cheers

Answer 1

You should vary the logic to your meet your requirements. For example:
the interview is complete if
. ForAllScope(the children)
.. either
... both
.... the child has toys; and
.... Forall(the child's toys, the name of the toy is known)
.. or
... the child does not have toys
You can adjust the above logic to suit your specific needs. For example, do you require the number of toys be at least 1 when the child has toys, or is it OK for a child to have toy's but not list any specific instances of toys?, can more than one toy of the same child have the same name?, etc.
Not to confuse things, but you could drive a more efficient interview by determining "the child has a toy" and/or "the child has toys" and/or "the child has at least 1 toy" based on the number of toys specified for each child (i.e. whether 0, 1 or more toys were associated with each child).
