Chapter 12 Creating Mappings
In a Logical Data Model (LDM), you can map entities, relationships, and inheritances from one LDM to another to express a simple correspondence between model objects. If you have various LDMs, each representing a separate part of your information system, for example, you may want to link equivalent concepts between these various models, and further define the links between their objects.
