Attribute groups are children of a package
and consist of attributes.
Attribute groups can be reused by referencing the groups in other
parts of the model or from other data models.
To define an attribute globally and reuse the attribute, define
the attribute as part of an attribute group.
The attribute group must have the GroupAttribute property.
An attribute in an attribute group has the following properties:
- Data type or domain name
- Length, precision, or scale
- Default value
- Derived
- Derivation expression
- Abbreviation
The following common properties are inherited from the SQL object
by the attribute group and the attributes in the group:
- Name, label, and description
- Annotations
- URLs
- Dependencies
