Enabling Many-to-many Relationships in an LDM

In an LDM, many-to-many relationships are, by default, not permitted and are represented with an intermediary entity. If you allow many-to-many relationships, you can select the many-to-many value in the cardinalities tab.

  1. Select Tools > Model Options.
  2. Select the Allow n-n relationships check box in the Relationship groupbox, and then click OK to return to the model.
    Note: When generating an LDM from a CDM, you can authorize the generation of many-to-many relationships by clicking the Configure Model Options button on the General tab of the generation dialog, and selecting the Allow n-n relationships option.
