In addition to modifying and using the standard domains supplied with the product, you can also create your own domains that work in exactly the same way.
To add a domain in the Domain Dictionary dialog, open the New Domain dialog and select an existing domain as the parent of the new domain from the Domain Parent list. By default, all the parent domain's inheritable properties migrate to the child domain. To override any of the child's properties, you can select the child domain from the Domain list and edit the properties using the Domain Dictionary dialog.
The domains inherit all their properties from their parent domain. When you drag a domain to a table, a new column is added in that table. The new column inherits all its properties from the domain. Once you add a column in a table, you can use on-diagram editing to change its name and use the Columns dialog to change other properties.
The non-inheritable domain properties, such as domain name and domain comment, never migrate to the domain or newly-created column.
