摘要
对传统的数据流法进行了改进:一方面,对数据流的流动作了严格的限制,增加了加工的逻辑独立性;另一方面,对DFD的布局作了3个分区,增加了DFD的可读性.
In support of the software development based on software bus technique at requirements analysis stage, this paper puts forward an improvement of the traditional data flow approach. By increasing the logical independence of processes, the movements of flows in DFD are strictly restricted. On the other hand, the layout of DFD is divided into three partitions in order to increase the readability of DFD.
