《结构化分析与系统规格说明》（Structured Analysis and System Specification，Tom DeMarco 著）中所描述的 Data Flow Diagrams（数据流图）非常轻量，并提供了一种以数据流动为核心来描述系统的通用方式。书中还深入探讨了如何应用它，比如画简明图表的价值……
Data Flow Diagrams as described in "Structured Analysis and System Specification" (Tom DeMarco) are lightweight and provides a common way to describe a system with a focus on the flow of data. The book also goes into detail on how to apply it. e.g., the value of having simple diagrams…
不妨先设想一下，用一个互联的微型计算机网络来实现图中所示的需求，每个气泡对应一台微型计算机。——《结构化分析与系统规格说明》（Structured Analysis and System Specification），Tom DeMarco，1978。
Just for the moment, consider the idea of implementing the requirements shown in the figure using a network of connected microcomputers, one microcomputer per bubble. Structured Analysis and System Specification, Tom DeMarco, 1978.
