Domain Properties

You can modify an object's properties from its property sheet. To open a domain property sheet, double-click its Browser entry in the Domains folder. The following sections detail the property sheet tabs that contain the properties most commonly entered for domains.

The General tab contains the following properties:

Property	Description
Name	Specifies the name of the item, which should be clear and meaningful, and should convey the item's purpose to non-technical users.
Code	Specifies the technical name of the object, which is used for generating code or scripts.
Comment	Descriptive comment for the object.
Stereotype	Extends the semantics of the object beyond the core UML definition.
Data type	Form of the data corresponding to the domain ; numeric, alphanumeric, Boolean, or others
Multiplicity	Specification of the range of allowable number of values attributes using this domain may hold. The multiplicity of a domain is useful when working with a multiple attribute for example. The multiplicity is part of the data type and both multiplicity and data type may come from the domain. You can choose between: 0..1 – zero or one 0..* – zero to unlimited 1..1 – exactly one 1..* – one to unlimited * – none to unlimited

The tables below indicates the data types for which you can specify:
