The Resource relates to Action as M:M via Permission join table/separate entity. User can have many permissions. The same permission may be assigned to multiple users.

How to define User-Permission relation as M:M? How would it look like in EF?

Just an idea - should there be a terenary relationship in there? There seems to be a three way relationship between the resource, permission and the user.

  • Yes, it seems to be a ternary relationship. – lexeme Jan 15 '15 at 7:43
  • Just don't know how to deal with (join) tables? – lexeme Jan 15 '15 at 7:44
  • Can you show the tables in logical form? there are not fks there. Did you add in the terenary relationship. If normalised properly the JOIN query should be simple. – Treasa Jan 15 '15 at 12:01
