  An $n$-FC ring is a left and right coherent ring whose left and right self
FP-injective dimension is $n$. The work of Ding and Chen in \cite{ding and chen
93} and \cite{ding and chen 96} shows that these rings possess properties which
generalize those of $n$-Gorenstein rings. In this paper we call a (left and
right) coherent ring with finite (left and right) self FP-injective dimension a
Ding-Chen ring. In case the ring is Noetherian these are exactly the Gorenstein
rings. We look at classes of modules we call Ding projective, Ding injective
and Ding flat which are meant as analogs to Enochs' Gorenstein projective,
Gorenstein injective and Gorenstein flat modules. We develop basic properties
of these modules. We then show that each of the standard model structures on
Mod-$R$, when $R$ is a Gorenstein ring, generalizes to the Ding-Chen case. We
show that when $R$ is a commutative Ding-Chen ring and $G$ is a finite group,
the group ring $R[G]$ is a Ding-Chen ring.
