In: Nenad Medvidovic and Richard N. Taylor (2000). [clarification needed], A system architecture primarily concentrates on the internal interfaces among the system's components or subsystems, and on the interface(s) between the system and its external environment, especially the user. It is the job of the software architect to find and talk to the right people about them -- the system "ilities." An architecture consists of the most important, pervasive, top-level, strategic inventions, decisions, and their associated rationales about the overall structure (i.e., essential elements and their relationships) and associated characteristics and behavior. relationships between elements). It is based on the use of multiple, concurrent views. (In the specific case of computer systems, this latter, special, interface is known as the computer human interface, AKA human computer interface, or HCI; formerly called the man-machine interface. For example, an architecture may have a data access layer which describes a set of services that read and write large sets of data—it is natural that such a system gets functionally assigned to the database team, which already has the required skill sets. System architecture conveys the informational content of the elements consisting of a system, the relationships among those elements, and the rules governing those relationships. Its usefulness is in conceiving and expressing the functional and nonfunctional quality characteristics along with the proposed form/structure of the software system.
