POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
This association asserts that an activity which is a member of an activity class is required in order to satisfy an obligation.
- contract (O, K: contract(contract_activity_type))
- These are the contracts that provide specifications, requirements, or other information about this type of activity. For example, a contract may describe the manner in which this type of activity is performed. Each contract_activity_type may be a subject of one contract.
- contractual_obligation (O, K: contractual_obligation(contract_activity_type)) (C054)
- This is the contractual obligation that requires the type of activity. Each contract_activity_type may be required by one contractual_obligation.
- activity_class (M, K: activity_class(contract_activity_type)) (C054)
- The activity type which is specified by the contract or required by the contractual obligation. Each contract_activity_type must describe one activity_class.
- 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.
- 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 contract_activity_type 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 contract_activity_type 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 contract_activity_type may be depicted by one or more graphical_element. Inherited from e_and_p_data.
Local rules:
- Uniqueness Constraint
- contract, contractual_obligation, activity_class
- Instance Value Constraint (C051)
-
Each CONTRACT ACTIVITY TYPE must be instantiated with any combination of contract and contract_obligation.
