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

Surrogate key of the table.


activity_s (FSK, M: CHAR VARYING(19))
activity_t (M: CHAR VARYING(16))

activity_classification.activity
This activity classification associates an activity with an activity class.
activity_s: Implements a foreign key to a row in one of the tables projected from entity activity depending on the value of the next column (See below).
activity_t: Defines the name of the referenced table. Possible values are defined in @activity.


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

activity_classification.activity_class
This is the activity class that this association assigns to the activity it is related to.

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.


end_time (O: TIMESTAMP)

transient_association.end_time
End time of the association.


start_time (O: TIMESTAMP)

transient_association.start_time

caused_by_s (FSK, O: CHAR VARYING(19))
caused_by_t (O: CHAR VARYING(16))

transient_association.caused_by
Specifies the activity which establishes this association.
caused_by_s: Implements a foreign key to a row in one of the tables projected from entity activity depending on the value of the next column (See below).
caused_by_t: Defines the name of the referenced table. Possible values are defined in @activity.


r_transient_period (FNK, O: CHAR VARYING(40))

transient_association.ref_transient_period
The type of period over which the property applies, such as day, month, quarter, cumulative, etc.
Defines a foreign key to table r_transient_pd.


terminated_by_s (FSK, O: CHAR VARYING(19))
terminated_by_t (O: CHAR VARYING(16))

transient_association.terminated_by
Specifies the activity which established the termination of a transient association between two objects.
terminated_by_s: Implements a foreign key to a row in one of the tables projected from entity activity depending on the value of the next column (See below).
terminated_by_t: Defines the name of the referenced table. Possible values are defined in @activity.
