Defines the primary entity for a hierarchy or measuregroup 定义hierarchy或measuregroup的主实体。
To reduce the frequency of updates , we can send an update only when the original path and the replicated path diverge by a defined amount ( figure 1 ) ( it may then be necessary to run both the master entity and the replicate by the master process to compare them ) 为了降低更新的频率,我们可以只在原始路径和复制体的移动路径发生指定数量的偏离时才发送更新包(这可能需要在主处理器上同时运行主实体和其复制体的运动模拟,以用来对这两条路径进行比较) 。
For sa & d projects , redundant relationships are retained only when different entity occurrences of the detail entity are accessed by different access path . for sa & d projects , any double v structures ( two detail entities are having the same two master entities ) are resolved by either merging the two detail entities or inserting some missing entities 对于系统分析及设计的计划,任何双v型结构(即两个详细数据实体拥有两个相同的主实体)可以由两个方法处理:将两个详细数据实体合并,或加上一些数据实体。
