摘要
针对二维表父子关系存储结构的不足,提出基于XML半结构化数据的新型产品结构解决方案。设计了基于XML的可重用构件库,以提高产品设计效益;同时提出以踪迹树为核心的产品结构树动态联接思想,以平衡系统的存储与计算能力;给出了踪迹树向产品结构树的映射算法,并提出了可屏蔽系统复杂性的产品结构服务模型。
To overcome the limitations of traditional parent-child model of product data, a new product structure model is proposed which employees XML semi-structured data. The XML-based reusable product components library is designed to be more efficient for product design. At the same time, the idea of trace-tree-centered dynamic construction, which can balance the system storage power and calculating power, is proposed. The mapping algorithm from trace-tree to product structure tree, as well as a service-based application solution that can shield the complexity of the details of the product data service, are brought forward.
