An Architectural Description Language for Enterprise Computing

Architectural description languages (ADLs) are used to specify high-level, compositional view of a software ap-plication. ADLs usually come equipped with a rigourous state-transition style semantics, facilitating specification and analysis of distributed and event-based systems. However, enterprise system architectures built upon newer middleware (implementations of Java’s EJB speci-fication, or Microsoft’s COM+ /.NET) require additional expressive power from an ADL. The ADL is de-signed to meet this need. In this paper, we describe several aspects of which facilitate specification and anl-ysis of middleware-based architectures for the enterprise. 1
