Attributes

Design Phase Tasks	P	E	Scoping Objects	Note
1.Add an attribute and transform it.	M	S	Entity type
2.Delete an attribute.	D	D	Entity type	2
3.Detail theproperty of an attribute.	D	D	Entity type	2, 4
4.Copy an attribute from one entity type to another.	A M	S S	Source entity type Target entity type	2
5.Move an attribute from one entity type to another	D M	D S	Source entity type Target entity type	2

Notes:

The subset task recommendations in Data Modeling Before Transformation allow the transformation. No special modifications are required. Expansion of the root subject area automatically provides the database with Delete protection, which enables transformation.
Scoping an entity type with Modify protection includes its associated data table with Delete protection and the database for that data table with Delete protection also.
If the entity type you are adding is a stand-alone, scope any data table of any entity type, and specify Modify protection.
An attribute or relationship that is referenced in a view cannot be deleted. The Objects Preventing Delete report identifies scoping objects define a subset that contains all references.
