  The existing data obtained in deep-inelastic scattering (DIS) experiments in
the kinematical region $x_B \approxle 10^{-2}$ and $Q^2 \ge 5 {GeV}^2$ are
examined to gain further insight into the dynamics of interacting gluons. It is
shown that not only the regularities observed in diffractive scattering and
those found in large-transverse-momentum jet production, but also the striking
features of the structure function $F_2(x_B,Q^2)$ observed in normal DIS-events
in this kinematical region can be understood as direct consequences of
self-organized criticality. The results explicitly demonstrate the usefulness
of concepts and methods of Complex Sciences in understanding the various
striking features observed in high-energy collision processes in which ``soft''
gluons play the dominating role.
