Hi all,
if
ADDRESS AND PARENT ARE dentifying relationships since child instance
can't exist
without parent.
IF CLINIC AND SERVICE are non-identifying since
they are independent entites and have no strong
dependence.Fine.
How about 1:1 relationship between ITEM and
ITEMPICTURE is this identifying or non??
How about 1:N relationship between ITEM and
ORDERED ITEM
how do you justify these are
NON-identifying??
Please provide me with a few concrete example of
mapping all kinds of relationships
while mapping an object model to data
model....
Thanks in advance
Martin
