POSC Specifications: Epicentre Version 3.0 | Relational Implementation |
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.
- instance_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- instance_create_date (O: TIMESTAMP)
- e_and_p_data.instance_create_date
This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance.
- last_updated (O: TIMESTAMP)
- e_and_p_data.last_updated
This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships).
- activity_s (FSK, M: CHAR VARYING(19))
- process_data_item.activity
Defines the Activity which used this process data item.
Defines a foreign key to table activity.
- description (O: CHAR VARYING(2000))
- e_and_p_data.description
A remark or comment about the instance.
- instance_creator (O: CHAR VARYING(80))
- e_and_p_data.instance_creator
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance.
- last_updated_by (O: CHAR VARYING(80))
- e_and_p_data.last_updated_by
This records the person or application making the update to this instance.
- source (O: CHAR VARYING(80))
- e_and_p_data.source
The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC".
- process_data_s (FSK, O: CHAR VARYING(19))
process_data_t (O: CHAR VARYING(30))
- 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_parameter_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_parameter.
Table is related to: data_collection_content, document_specification_part, @graphical_element
Primary Key Constraint on: INSTANCE_S
