Architecture Description Languages
Architecture description languages (ADLs) are formal languages that can be used to represent the architecture of a software-intensive system. As architecture becomes a dominating theme in large system development, methods for unambiguously specifying architecture will become indispensable. By architecture, we mean the components that comprise a system, the behavioral specifications for those components, and the patterns and mechanisms for interactions among them. Note that a single system is usually composed of more than one type of component: modules, tasks, functions, etc. An architecture can choose the type of component most appropriate or informative to show, or it can include multiple views of the same system, each illustrating different componentry.
