Hi,

Any one tell me the

Difference between Collection Cardinality and Selection Cardinality ?

Advance Thanks,

Namrata.

Namrata,

Collection Cardinality or Node Cardinality is a set of two values that define the minimum and maximum number of elements that a node may hold at run-time and is represented as (0..1), (1..1), (0..n), (1..n). The value on left denotes the minimum number of elements that a node must have at runtime and the value at right denotes the maximum number of elements that a node may have.

Node Selection Cardinality is again a set of two values like node cardinality but denotes the number of elements that may be selected at run-time. Selection cardinality must not violate Node collection cardinality i.e. if node cardinality is 0..1 0r 1..1, it is invalid to specify 0..n or 1..n as selection cardinality.

Link given by Fazal is a good resource to understand cardinality as such.

Hope this helps.

Vishwas.
