可执行体系结构研究

A Study of Executable Architecture

体系结构是系统设计与实施的蓝图,它能否正确、合理地指导实践在很大程度上依赖于体系结构的验证与评估。可执行体系结构研究为体系结构验证与评估开辟了新的途径。为了使各体系结构产品在整体上形成一个执行体,提出了可执行体系结构执行规则描述这一个概念。执行规则描述体系结构产品的执行、调用与数据流关系,为体系结构的执行提供了特定的背景信息。它通过标准的动态可执行模型接口分别调用该模型的执行引擎,从而达到体系结构在整体上执行的目的。体系结构的正确执行为体系结构验证提供依据,同时其运行结果为体系结构的评估提供依据。

Arehitecture is a blueprint of system design and implementation, and whether it can guide practice eorreetly largely depends on the architecture verification and evaluation. Executable architecture provides a new way to validate and evaluate the architecture. In order to make all architecture products into a whole executive entity, this paper puts forward a new eoneept-execufion roles description. Execution roles describe the execution, call and data flow relationship between architecture products, and thus provide special background information for the architecture execution. Through standard dynamic executive model interfaces, execution roles can call the models＇ executable engines, and then attain the aim to run the architecture on the whole. That architecture can nm successfully, providing justification for architectttre verification, and its executive result also provides justification for architecture evaluation.
