The data value used for a process parameter in a processing activity. For example, where the process considered is a computer program that has a ref process parameter that is the number of iterations of a calculation the program is performing, then the process data item might point to an instance of interprocess data which has an integer value with a value equal to 4 for one particular time this program is run, and 5 for the next time.

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

Surrogate key of the table.


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

process_data_item.activity
Defines the Activity which used this process data item.
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.


process_data_s (FSK, O: CHAR VARYING(19))
process_data_t (O: CHAR VARYING(16))

process_data_item.process_data
Defines the data instance which was used in the role defined by Process Parameter.
process_data_s: Implements a foreign key to a row in one of the tables projected from entity process_data depending on the value of the next column (See below).
process_data_t: Defines the name of the referenced table. Possible values are defined in @process_data.


process_par_s (FSK, O: CHAR VARYING(19))

process_data_item.process_parameter
Defines the role of the data in the activity which used it.
Defines a foreign key to table process_par.
