Logical Display Levels

The Logical Display levels are as follows:

Entity

Displays the name of each entity in a data model inside an entity box. No other information displays for the entity.

Attribute

Displays the attributes for each entity in a data model, with the primary key attributes above the line and the non-key attributes below the line in an entity box.

Primary Key

Displays the primary key attributes (those found above the line in an entity box) for each entity in a data model. The attributes below the line are hidden, but display when you switch back to the Attribute Display Level and you can also see them in the Attribute Editor.

Keys

Displays primary key attributes above the line and does not display any non-key attributes below the line in an entity box. Entity boxes have two attribute boxes; the upper populated with the PK attributes and the lower populated with the attributes belonging to all key types except PK.

Definition

Displays the definition for each entity in a data model.

Icon

Displays the bitmap, if you have assigned one to the entity. You can assign a different bitmap to each entity in the Icon tab of the Entity Editor.
