如果规则绑定涉及多于两个表时，在InfoSphere DataStage任务开始时，级联多个连接阶段。

If the rule bindings involve more than two tables, several join stages are cascaded at the beginning of the InfoSphere DataStage job.

图8展示了如果规则使用了多个参考列，那么左外部连接就进行级联。

Figure 8 shows that the left outer join operations are cascaded if a rule USES more than one reference column.

本文采用耦合映像格子的方法研究了带有偏好连接的群落网络的级联失效问题。

In this paper, cascading failure is studied by coupled map lattices methods in preferential attachment community networks.
