What is the difference between the continuous-time Fourier transform and the discrete-time Fourier transform?

The continuous-time Fourier transform is evaluated over the unit circle of the z-domain, while the discrete-time Fourier transform is evaluated on the Laplace s-domain's imaginary line

The continuous-time Fourier transform is evaluated on the Laplace s-domain's real line, while the discrete-time Fourier transform is evaluated over the unit circle of the z-domain
