This survey deals with the spaces \(S^ r_ pL\) and \(S^{\alpha}_{p,\theta}B\) of Sobolev and Besov type, respectively, having dominating mixed smoothness properties. The authors describe decomposition procedures, characterizations via approximation and Fourier-analytical methods of Paley-Littlewood type. Finally the peiodic case is considered.
