Beyond Definition/Use: Architectural Interconnection
Robert Allen, and David Garlan
Proceedings of the ACM Interface Definition Language Workshop, January, 1994.
|Large software systems require decompositional mechanisms in order to make them tractable. Traditionally, MILs and IDLs have played this role by providing notations based on definition/use bindings. In this paper we argue that current MIL/IDLs based on definition/use have some serious drawbacks. A significant problem is that they fail to distinguish between "implementation" and "interaction" relationships between modules. We propose an alternative model in which components interact along well-defined lines of communication - or connectors. Connectors are defined as protocols that capture the expected patterns of communication between modules. We show how this leads to a scheme that is much more expressive for architectural relationships, that allows the formal definition of module interaction, and that supports its own form of automated checks and formal reasoning.|
