    • Methods for product data management and corresponding systems and computer-readable mediums. A method includes maintaining a hierarchical data structure for a complex item. The data structure includes a root node representing the complex item, at least one assembly node associated with a the partition node, and a plurality of part nodes each associated with the assembly node. The method includes defining at least two occurrences associated with the root node and corresponding to at least the root node and assembly node. The method includes defining at least one partition node representing a partition of the complex item, the partition node representing an organizational division of the occurrences of the associated with the root node that can be referenced in queries and navigation. The method includes associating at least two of the plurality of occurrences with the at least one partition node.
    • 产品数据管理方法和相应的系统和计算机可读介质。 一种方法包括维护复杂项目的分层数据结构。 数据结构包括表示复杂项的根节点,与分区节点相关联的至少一个组装节点,以及每个与组装节点相关联的多个部分节点。 该方法包括定义与根节点相关联并且至少对应于至少根节点和汇编节点的至少两次出现。 该方法包括定义表示复杂项目的分区的至少一个分区节点,分区节点表示与查询和导航中可引用的根节点相关联的事件的组织划分。 该方法包括将多个出现中的至少两个与至少一个分区节点相关联。
