  Symbiotic stars are strongly interacting binaries, consisting of a white
dwarf and a cool giant, mainly of spectral type M. AG Draconis belongs to a
less numerous group of the yellow symbiotic systems, as the cool component in
this binary is of a spectral type earlier than K4. Recently, after seven years
of quiescence, this symbiotic star exhibited a very unusual active stage with
the four minor outbursts observed. Thanks to the excellent involvement of
amateur astronomers and professional observatories, we can study the activity
of AG Draconis in unprecedented details. In the present work, we discuss the
activity and peculiarities of this interacting system within the entire group
of symbiotic stars whose properties have recently been presented in our New
Online Database of Symbiotic Variables.
