Which of the following in an attribute cannot be modified after its creation?
-
Type
-
Ranges
-
Default Value
-
Name
-
Vault
A
Correct answer
Explanation
In Matrix/3DX PLM systems, an attribute's data type is locked at creation and cannot be changed later. This is a fundamental schema design principle - changing a type would break existing data and require database migration. Ranges, default values, and names can typically be modified through schema updates or admin tools without affecting the core data structure.
