Note that for aDAG represented in Matrix, shifting position of entire row or entire column still makes the representation equivalent.
注意,一个DAG表示为矩阵,移位置的整行或整列仍然是等效的表示。

Furthermore, an algorithm of certificate chain processing is presented, which searches the DAGs, and aDAG by depth-first-algorithm, and inter-DAGs by breadth-first-algorithm.
Oozie workflow is a collection of actions (i.e. Hadoop Map/Reduce jobs, Pig jobs) arranged in a control dependency DAG (Direct Acyclic Graph), specifying a sequence of actions execution.
Oozie工作流是放置在控制依赖DAG(有向无环图 Direct Acyclic Graph)中的一组动作(例如,Hadoop的Map/Reduce作业、Pig作业等),其中指定了动作执行的顺序。
