  We consider mixed normed Bergman spaces on homogeneous Siegel domains. In the
literature, two different approaches have been considered and several results
seem difficult to be compared. In this paper we compare the results available
in the literature and complete the existing ones in one of the two settings.
The results we present are: natural inclusions, density, completeness,
reproducing properties, sampling, atomic decomposition, duality, continuity of
Bergman projectors, boundary values, transference.
