What symbols are used in IDEF1X diagrams to represent cardinalities?

What will be an ideal response?

In IDEF1X, nonidentifying connection relationships have a default cardinality of one-to-many, with a mandatory parent and optional child. This is represented by placing a filled-in circle by the child. The same notation is the default for identifying connection relationships. Nonspecific relationships place a filled-in circle at each end of the connecting line, but there is no way to indicate a minimum cardinality. Additional symbology that may be used is a diamond next to the parent to indicate that it is optional, a P to indicate "one-or-more", and a Z to indicate "zero-or-one."
