We investigate the exclusive semileptonic decays of (B,B{sub s};D,D{sub s}) mesons into less heavy as well as light mesons in a field-theoretic framework based on the independent quark model with a confining potential in scalar-vector-harmonic form. With the recoil effect properly taken into account, the present model describes consistently the semileptonic decays of charmed and b-flavored mesons, agreeing well with the experimental data. The transition form factors in the heavy to heavy decays, in particular, comply with the heavy quark symmetry relations expected from HQET. The CKM parameters extracted in this formalism are close to the existing data. The model prediction also satisfies the Isgur-Wise relation connecting the form factors of the semileptonic (B{r_arrow}{rho}e{nu}) and that of rare radiative decay (B{r_arrow}{rho}{gamma}). {copyright} {ital 1997} {ital The American Physical Society}
