<div><p>A dependent file must be a physical file with a maximum of one
|

member. You can create a dependent file as you do any physical
|
|
file or use an existing file.</p>
|
|
<p>The dependent file does not require a keyed access path when you create
|
|
the actual constraint. If no existing access paths meet the foreign key criteria,
|
|
the system adds an access path to the file.</p>
