POSC Meta Model Specifications Version 2.3 |
Meta Data Relational Implementation |
This entity stores the changed objects, resulting from a change. A change request is grouped into changes, where each change may have a title and description and a set of changed objects.
- changed_object_s (PK, M: CHAR VARYING(19))
- Surrogate key of the table.
- object_nm (M: CHAR VARYING(80))
- changed_object.object_nm
Fully specified name of the changed object.
- object_t (M: CHAR(3))
- changed_object.object_t
This is the type of the object that has changed. Possible values currently supported are: ENT : Entity ATT : Attribute TYP : Type EPT : Epicentre/simple type UNR : Uniqueness rule WHR : Where rule SUP : Supertype rule
- top_object_nm (M: CHAR VARYING(80))
- changed_object.top_object_nm
Name of the entity, type or diagram that the changed object belongs to.
- top_object_t (M: CHAR(3))
- changed_object.top_object_t
Type code of the entity, type or diagram that the changed object belongs to. So possible values are: ENT, TYP and DIA.
- parent_change_s (FSK, M: CHAR VARYING(19))
- changed_object.parent_change
The change that caused this object to change.
Defines a foreign key to table change.
- object_s (O: CHAR VARYING(19))
- changed_object.object_s
This is the surrogate key for the object that has changed, unless it has been deleted. If the object was deleted it will be NULL. Depending on the object_t contents it points to one of the following entities: ENT : entity_def ATT : atribute TYP : type_def EPT : epic_type UNR : rules WHR : rules SUP : Supersub ERD : Entity Relationship Diagram
- top_object_s (O: CHAR VARYING(19))
- changed_object.top_object_s
Surrogate key of the entity, type or diagram that the changed object belongs to. If the object was deleted and the entity, type of diagram the object belonged to was deleted as well, this will be NULL.
Primary Key Constraint on: CHANGED_OBJECT_S
