Creating an Attribute

You can create an entity attribute using the following tools, available on the Attributes tab in the property sheet of an entity, association, or inheritance:

Tool	Description
	Add a Row – Creates a new attribute and associated data item (with the same name and code). If you have enabled the Allow Reuse model option, the new data item can be used as an attribute for other objects. If you have enabled the Allow Reuse and Unique Code model options and you type the name of an existing data item, it will be automatically reused.
	Add Data Item (CDM)/Add Attributes (LDM) - Opens a Selection window listing all the data items/attributes available in the model. Select one or more data items/attributes in the list and then click OK to make them attributes to the object. If the data item/attribute has not yet been used, it will be linked to the object. If the data item/attribute has already been used, it will be copied (with a modified name if you have enabled the Unique code model option) and the copy attached to the object.
