Entities (CDM/LDM)

An entity represents an object about which you want to store information. For example, in a model of a major corporation, the entities created may include Employee and Division.

When you generate a PDM from a CDM or LDM, entities are generated as tables.

• Creating an Entity
  You can create an entity from the Toolbox, Browser, or Model menu.
• Entity Properties
  To view or edit an entity's properties, double-click its diagram symbol or Browser or list entry. The property sheet tabs and fields listed here are those available by default, before any customization of the interface by you or an administrator.
• Copying Entities
  You can make a copy of an entity within the same model or between models. When you copy an entity, you create a new entity with a new name and code, attributes, and identifiers. Model options control whether you create new data items or reuse the data items that are attached to the original entity.
• Displaying Attributes and Other Information on an Entity Symbol
  To set display preferences for entities, select Tools > Display Preferences, and select the Entity sub-category in the left-hand Category pane.
