摘要：I present results showing connections between different types of accreting objects. I show the
known empirical connections between X-ray binaries and Active Galactic Nuclei, the fundamental
plane of black hole activity and the variability plane, as well as highlight some of their applications.
In addition, I will argue that also neutron stars and white dwarfs may be included into a
single unified scenario of accreting sources.
