System Architecture is a broad concept related to the handling of objects (existing or to be created) known as “systems"". The systems in one way or the other support the reasoning about the structural properties of these objects.
A system architecture or systems architecture refers to a concrete model that describes the arrangement, behavior, and more views about a system. System architecture includes system constituents, externally visible properties of those components and the relationships or behavior between them.
Thus, one can say that system architecture refers to the following:
- The architecture or model of a system
- Methodology adopted to build an architecture
- Acquire knowledge related to constructing systems
