POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
Data which is not otherwise instantiated in the data store and which flows between processes in a processing stream. A "value" may or may not be defined. Knowledge of the ref process parameter value is required in order to understand the data value.
- process_parameter (O, K: process_parameter(interprocess_data))
- Defines the role of the data in the activity which created it. Each interprocess_data may be a one process_parameter.
- activity (O, K, I: activity(process_data))
- Defines the activity which created this instance. Each interprocess_data may be the result of one activity. Inherited from process_data.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- instance_create_date (O, I: ndt_date_tod) (C126)
- 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. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- integer_value (O: ndt_int4)
- An integer parameter value without units.
- last_updated (O, I: ndt_date_tod) (C126)
- 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). Inherited from e_and_p_data.
- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- quantity_value (O: ndt_any_quantity)
- A real parameter value with units.
- real_value (O: ndt_real4)
- A real parameter value without units.
- source (O, I: ndt_identifier) (C126)
- 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". Inherited from e_and_p_data.
- string_value (O: ndt_name)
- A string parameter value.
- text_value (O: ndt_text)
- Parameter data encoded as characters in a string.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each interprocess_data may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each interprocess_data may be included in one or more document_information_content. Inherited from e_and_p_data.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each interprocess_data may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- process_data_item (I, V: SET[0:?] process_data_item(process_data))
- Defines where this data was used by an activity. Each interprocess_data may be the value for one or more process_data_item. Inherited from process_data.
Local rules:
- Uniqueness Constraint
- process_parameter, activity
- Same Related Instance (C047)
-
The TYPICAL ACTIVITY which is related to PROCESS PARAMETER must be the same TYPICAL ACTIVITY which is related to the creating ACTIVITY.
