基于PDA的生猪溯源管理系统对象模型设计

Object Model Design of PDA-based Pig Traceability Management System

采用面向对象的软件工程方法对基于PDA的生猪溯源管理系统进行建模,通过用例图、类图、协作图和状态图的设计,用统一建模语言UML实现了对系统对象的建模。该面向对象的模型为基于PDA的生猪溯源管理系统的实现提供了稳定性好、可重用性高、适应性强、易于维护的软件蓝图。

Using object-oriented software engineering method, we build the model of PDA-based pig traceability management system, and through designing use case diagrams, class diagrams, collaboration diagrams and state diagrams, achieve system object model by Unified Modeling Language （UML）. The object-oriented model provides a software blueprint with good stability, high reusability, strong adaptability, easy maintenance for implementing PDA-based pig traceability management system.
