The association of a material with a material class. Classification is the result of an activity which compares the characteristics of a material with the specified characteristics of the class.

material_clsn_s (PK, M: CHAR VARYING(19))

Surrogate key of the table.


material_class_s (FSK, M: CHAR VARYING(19))

material_classification.material_class
Specifies the material class being applied to the material.
Defines a foreign key to table material_class.


description (O: CHAR VARYING(2000))

transient_association.description
A description of the transient association.


duration (O: FLOAT)
duration_u (FNK, O: CHAR VARYING(15))

transient_association.duration
Defines the duration of the association expressed in any valid units of time.
duration_u: Defines the unit of measure. Defines a foreign key to table r_uom.
