POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
This association links two activities where one activity (pointed to by the "caused_by" attribute) causes another activity (pointed to by the "results_in" attribute)to happen. For example, an activity of spilling hazardous chemicals may result in a clean-up activity. In Epicentre, the activity_cause_and_effect entity would link the "caused_by" activity of spilling hazardous chemicals to the "results_in" activity of cleaning up.
- caused_by (M, K: activity(caused))
- This is the activity that was the cause of the cause and effect association. For example, an activity of spilling hazardous chemicals may result in a clean-up activity. In Epicentre, the activity_cause_and_effect entity would link the "cause" activity of spilling hazardous chemicals to the result activity of cleaning up. This attribute points to the "cause" activity. Each activity_cause_and_effect must caused by one activity.
- result (M, K: activity(result_of))
- This is the activity that is the result of this activity cause and effect association. For example, an activity of spilling hazardous chemicals may result in a clean-up activity. In Epicentre, the activity_cause_and_effect entity would link the activity of spilling hazardous chemicals to the "result" activity of cleaning up. This attribute points to the "result" activity. Each activity_cause_and_effect must result one activity.
- 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.
- intentional (O: ndt_boolean)
- This attribute is used to describe the fact that one activity was intended to cause another activity to occur. If "True", then the cause was intended, if "False" then it was not intended.
- 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.
- 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.
- 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 activity_cause_and_effect 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 activity_cause_and_effect 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 activity_cause_and_effect may be depicted by one or more graphical_element. Inherited from e_and_p_data.
