I have written the following query for purposes of finding the instances of my module within the system:

    USE [DotNetNuke_FogBugz_Module_Dev];

    SELECT m.ModuleID, [md].[ModuleDefID], [dm].[DesktopModuleID], dm.FriendlyName FROM
                              ([DesktopModules] dm INNER JOIN [ModuleDefinitions] md ON (dm.DesktopModuleID = md.DesktopModuleID) 
                                INNER JOIN Modules m ON (m.ModuleDefID = md.ModuleDefID))
                          WHERE dm.FriendlyName = 'My Module Name';



It returns (as expected) the two module instances that I presently have installed in my DNN portal, the first with a ModuleID of 375, and the second with a ModuleID of 377. 

Both records returned from the query have the same ModuleDefID (109) and DesktopModuleID (67). 

In terms of uniquely identifying only module instances that are in my portal, and are of the type of the module I am developing, do I have all of the unique keys required to create a related weak entity? (see diagram below)
 

Thank you,
    Andrew J. Leer

Andrew, while DesktopModuleID is required for the module to be properly registerd in DotNetNuke, you should not create a key against it. By creating a foreign key against the Modules table (the one you should use), it will handle cascading deletes when a module is deleted (from a page and recycle bin, or uninstalled). Basically, the DesktopModules table is part of the module's definition and registration in DotNetNuke (ie. 1 DesktopModule record can have multiple ModuleDefinitions records), while the Modules table really represents placement of a ModuleDefinition (this is also joined on TabModules for complete 'placement' details).

Should I just be using the Personalization Settings instead of adding a foreign key to the table?

What I'm working on is just an administration interface for a module, so I doubt it would matter performance wise.
