支持在ArchWare ADL中不断发展的软件体系结构
Support for Evolving Software Architectures in the ArchWare ADL
摘要：
不能进化的软件注定会萎缩：它不能适应不断的修改和重新协商其业务目标，也不能拦截新技术的潜力。为了适应软件系统的变化，我们定义了一个主动软件体系结构：动态的，因为组件的结构和基数以及交互在执行过程中是可变的;可更新的，因为组件可以被替换;可分解的，因为执行系统可以被替换。（部分）停止并分裂成其组成部分和相互作用;并且反射性在于组件和交互的规范可以在执行期间演进。在这里，我们描述的设施的ArchWare体系结构描述语言（ADL）指定活动的体系结构。这项工作的贡献是概念的独特组合，包括：基于π演算的通信和表达语言，用于指定可执行架构;超代码作为系统执行的底层表示，可用于内省;分解运算符，以逐步打破执行系统;和结构反射，用于创建新组件并将其绑定到运行的系统。
英文摘要：
Software that cannot evolve is condemned to atrophy: it cannot accommodate the constant revision and re-negotiation of its business goals nor intercept the potential of new technology. To accommodate change in software systems we have defined an active software architecture to be: dynamic in that the structure and cardinality of the components and interactions are changeable during execution; updatable in that components can be replaced; decomposable in that an executing system may be (partially) stopped and split up into its components and interactions; and reflective in that the specification of components and interactions may be evolved during execution. Here we describe the facilities of the ArchWare architecture description language (ADL) for specifying active architectures. The contribution of the work is the unique combination of concepts including: a π-calculus based communication and expression language for specifying executable architectures; hyper-code as an underlying representation of system execution that can be used for introspection; a decomposition operator to incrementally break up executing systems; and structural reflection for creating new components and binding them into running systems.
