The holomorphic vector bundles can be described with help of flat bar partial-connections. We extend this description to arbitrary coherent sheaves. This is done with help of SUPER bar partial-connections. The notion of a super connection is understood in the same way as in a work of Quillen. Super connections allow us to get an alternative approach to characteristic classes and to the derived category of coherent sheaves.
