Let D be a Dedekind domain and G be a periodic Abelian-by-finite group. In this paper we study DG modules in which every factor-module, apart from the trivial one, is DG -Artinian. In particular we prove that such modules cannot be D -periodic and that G must be subject to some restrictions. Finally, we give a detailed description of such modules when G is periodic Abelian and the spectrum of D is infinite.
