Defining identifiers

Defining identifiers

An identifier is a class attribute, or a combination of class attributes, whose values uniquely identify each occurrence of the class. An identifier is the OOM equivalent of a CDM identifier or a primary key or an alternate key in a PDM.

Each class must have at least one identifier. If a class has only one identifier, than it is designated by default as the primary identifier for the class. A primary identifier is the main identifier for a class.

You can attach attributes or business rules to an identifier.

Identifier properties

An identifier has the following properties:

Property	Description
Name	Name of the identifier

Code	Reference name for the identifier

Comment	Descriptive comment for the identifier

Class	Name of the class to which the identifier belongs to

Primary	Indicates that the identifier is the primary identifier of
identifier	the class. There can only be one primary identifier for
	a given class
