This method includes two stages and four levels, the first stage: rebuilding data flow and control flow of the software, this stage includes module level mapping and function level mapping.

第一阶段：重构软件的数据流程和控制流程。该阶段包括模块级映射和函数级映射。

The inputs and outputs can be pure control-flow links as in the models in the previous section, or can be data flow links as shown in Figure 5.

这些输入和输出可以是纯控制流链接(类似于上一部分中的模型)，也可以是类似于图5所示的数据流链接。

A start node can only issue control flow, while stop and end nodes can also receive data flow.

开始节点只能发出控制流，而停止和结束节点还可以接收数据流。
