Ionic Compounds are compose of a Metal and Non Metal element bonded via transfer of electron from the cation to anion to form a stable compound. They are form from electrostatic interactions of ions, in which causes them to have higher melting and higher boiling point, and only become a good conductor of electricity when it dissociate in a solution. While covalent compounds are formed via sharing of electron between two non metals. Typically they are of low melting and boiling point and are poor conductors of electricity.
