The Logical Data Model (LDM) is used to document the data requirements and structural business process rules of the architecture's operational view. It describes the data and information that is associated with the information exchanges of the architecture, in the scope and to the level of detail required for the purposes of the architecture.
To create an LDM diagram
1 Create a new IDEF1X diagram.
For more information, see the related topic in the help.
2 Add entities to the diagram to represent each person, place, event, or concept about which information will be maintained in the system.
3 Add relation lines between entities to represent associations.
