IDEF1X domains define a named set of possible values for an attribute.IDEF1X has two types of domains,base domains and type domains.A base domain is a domain with a data type and a value list or range definition.A type domain is a subset of a base domain or another type domain,and allows a domain hierarchy to be constructed.

The IDEF1X default cardinality of a nonidentifying connection relationship is one-to-one,with a mandatory parent and an optional child.
