农产品安全认证与可追溯系统面向对象体系结构研究

Study on Architecture of Farm Produce Safety Authentication and Traceability System Based on Object-Oriented Style

采用统一建模语言(UML)对种植业农产品安全认证与可追溯系统体系结构进行面向对象分析与设计。分别进行了需求收集、系统分析和系统设计。图例说明了由类图和行为图表述的农产品安全认证与可追溯系统逻辑体系结构和通过面向对象设计确定由构件图和配置图表述的农产品安全认证与可追溯系统物理体系结构。将UML所建立的体系结构模型映射成Colored Petri Net对体系结构进行评价,通过可达性分析与仿真优化了系统体系结构。

The Object-Oriented analysis and design approach based on Unified Modeling Language （UML） for planting farm produce safety authentication system architecture is put forward, by which logical architecture described by class diagrams and behavior diagrams can be developed through Object-Oriented analysis, and physical architecture described by component diagrams and deployment diagrams can be developed through Object-Oriented design. The method from UML artifact mapping to CPN is used to evaluate the logical, behavioral and performance of architecture by arithmetical analysis and simulation so that the system architecture can be optimized.
