We show that existing data on the semileptonic decays {ital D}{r arrow}{ital Ke}{sup +}{nu}{sub {ital e}} and {ital D}{r arrow}{ital K}{sup *}{ital e}{sup +}{nu}{sub {ital e}} provide information on matrix elements relevant for the rare {ital {bar B}}-meson decays {ital {bar B}}{r arrow}{ital Ke}{sup +}{ital e}{sup {minus}}, {ital {bar B}}{r arrow}{ital K}{sup *}{ital e}{sup +}{ital e}{sup {minus}}, and {ital {bar B}}{r arrow}{ital K}{sup *}{gamma} and that future data on {ital {bar B}}{r arrow}{rho}{ital e}{bar {nu}}{sub {ital e}} and {ital {bar B}}{r arrow}{pi}{ital e}{bar {nu}}{sub {ital e}} will further constrain them. A discussion of how the form factors for these latter decays are in turn determined by semileptonic {ital D} decays at the corresponding recoil momenta is also presented.
