When creating a domain you must choose the data type. In this case I want to create a Global Unique Identifier (GUID). Clicking on the data type lookup I am able to see more details for each data type (figure sorted by type).
In this list there are two Data types of Type “Guid”.
First question is what is the difference between these Data types?
Also what is the meaning of each attribute? And in particular does Calculated mean that columns of this type will not be stored in the database?
