We review the present status of CP violation in the standard model. Subsequently we make an excursion in the future in order to see what we could expect in this field in this and the next decade. We present various strategies for the determination of the CKM parameters and divide the decays into four classes with respect to theoretical uncertainties. We emphasize that the definitive tests of the Kobayashi-Maskawa picture of CP violation will come through a {\it simultaneous} study of CP asymmetries in $B_{d,s}^o$ decays, the rare decays $K^+ \to \pi^+\nu \bar\nu$ and $K_L \to \pi^o\nu\bar\nu$, and $x_d/x_s$. We illustrate how the measurements of the CP asymmetries in $B^0_{d,s}$-decays together with a measurement of $Br(K_L\to \pi^\circ\nu\bar\nu)$ or $Br(\kpnn)$ and the known value of $\mid V_{us}\mid $ can determine {\it all} elements of the Cabibbo-Kobayashi-Maskawa matrix essentially without any hadronic uncertainties.
