The invention is directed to the modeling of an object-
oriented system. In particular, a reference-based association
relating first and second classes is created by specifying a
reference attribute in the first class corresponding to the
second class, wherein the reference attribute in the first class
includes a type and cardinality. Objects from the first and
second class are instantiated and objects of the first class are
associated with objects of the second class using the reference
attribute, wherein the type included in the reference attribute
indicates that only objects instantiated from the second class
can be connected to the objects instantiated from the first
class, and the cardinality included in the reference attribute
indicates how many objects from the second class can be connected
to the objects of the first class. This is said to maintain
consistency between the classes and the objects in order to
provide an exact execution behavior for the objects instantiated
from the classes.
