A system architecture or systems architecture is the conceptual model that defines the structure, behavior, and more views of a system.
An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures of the system, which comprise system components, the externally visible properties of those components, the relationships (e.g. the behavior) between them, and provides a plan from which products can be procured, and systems developed, that will work together to implement the overall system. More recently, there have been efforts to formalize languages to describe system architecture, collectively these are called architecture description languages (ADLs).
Famous quotes containing the words systems and/or architecture:
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
“They can do without architecture who have no olives nor wines in the cellar.”
—Henry David Thoreau (1817–1862)
