  Systems definition is an artifact created by humans to describe what a system
is. A system has been defined, by systems definition 1.0, hopefully to be an
integrated whole, embodied in its components, their interrelationships with
each other and the environment, and the principles and guidelines governing its
design and evolution. This systems definition 1.0 defining the system possesses
one cardinal deficiency. The deficiency comes from that it does not describe
the integration of systems structure and systems behavior. Structure-behavior
coalescence (SBC) architecture provides an elegant way to integrate the
structure and behavior of a system. A system is therefore redefined, by systems
definition 2.0, truly to be an integrated whole, using the SBC architecture,
embodied in its assembled components, their interactions with each other and
the environment, and the principles and guidelines governing its design and
evolution. Since systems definition 2.0 describes the integration of systems
structure and systems behavior, definitely it is able to form an integrated
whole of a system. In this situation, systems definition 2.0 is fully capable
of defining a system.
