Object relationship 2005-01-05 - By Ramnish Kalsi

This would actually depend upon the usage. If the company object is not
complete without members information, then yes, you would have to load the
member information.
Alternately, if you do not need the information about the members, you could
either maintain a list of ID's of the organization (instead of whole
objects) , that this company is member of.
But, firstly, you should redefine your business model slightly - when you
say "a company is member of other companies", what exactly do you mean. Is
it an amalgamation of companies ?? If so, will the company object be
accurate depiction of this umbrella business entity. ?
think about these before you finalise your model.

Hi all,
a company can be member of other companies.
class company{
ArrayList membersOf;
}
when i load this company from database, do i have to load member companies
too?
if yes, i must load members of the members'. huh?
if no, nullpointer issue !!!
how do i handle that?
thanks.
