  Using unitarity, unlike the approaches available in the literature, we have
constructed 9 independent representations of CKM matrix starting with each of
the 9 elements of the matrix. The relationship of these independently
constructed representations with the already available ones in the literature
has been compared and discussed. Further, the implications of these
representations have been explored for some of the CKM parameters such as
\delta, J and \epsilon_k. Interestingly, we find that the PDG representation
which is equivalent to our first representation seems to be most appropriate to
incorporate the hierarchy of the elements of the CKM matrix as well as to
describe the related phenomenology.
