    hi, i know unitary transformation - but could not get where do we need finite and infinite unitary transformation ?

    It is not that "we need" or don't need, rather it is the nature of the symmetry group that decides for us. For example, non-compact groups such as the Lorentz group does not have finite-dimensional unitary representations.
