Thanks a lot Sir  Félix F. González-Navarro.

your answer helped me a lot.

homogeneous : i.e data that belong to the same cluster should be as similar as possible.

heterogeneous : i.e data that belong to different clusters should be as different  as possible.

I think data that can be represented with normal distribution (Gaussian) considered as Homogeneous data otherwise it is Heterogeneous.
