Summary:The derivation of the boson representation of spin operators is given which reproduces the Holstein-Primakoff and Dyson-Maleev transformations in the corresponding cases. The suggested formalism allows to address some subtle issues which appear crucial for treating certain class of problems. Moreover, the transformation is suggested which is naturally related to the symmetry of the spin systems.
