Hello All,
Please let me know about Cardinality concept in creating. node.... with small examples.
Thanks in advance.
Venkat.
hi venkat.....
cardinality is nothing but how many values can be stored in that node....
say, you have three attributes in a node....
if you give the cardinality of a node as 0..1
then the attribute can have either 1 value or no value.
if you give the cardinality of a node as 1..1
then the attribute should have only one value.
if you give the cardinality of a node as 0..n
then the attribute can have either n number of values or no value. so this will act like a table.
if you give the cardinality of a node as 1..n
then the attribute shold have atleast one value.
---regards.
