One:Many Child Relationships

For one:many relationships, the child record has a direct foreign key to the primary object. IDD supports two kinds of one:many relationships.

The following table describes the types of one:many child relationships:

Relationship	Description
One:Many	The list of child records will be displayed in a tab below the primary data.
Logical One:One	The expectation is that there should be only one child record for each primary object. The data is shown in the form with the primary object. If there is more than one child (due, for example, to two primary object records being merged), the IDD application provides a means to resolve this.
