1.DFD定义 2.Flow chart定义 3.DFD和Flow chart的区别 1.DFD 1.1DFD 定义 DFD, Data Flow Diagram. 它表示系统如何处理数据并描述数据的来源、去向以及数据的存储方式 如图: 1.2 DFD的组成 Process– Transforms incoming data flow into the outgoing data flow 输入数据流转化为输出数据流 Data Store– Represe...
流程:Flow 指特定主体为了满足特定需求而进行的有特定逻辑关系的一系列操作过程,流程是自然而然就存在的。但是它可以不规范,可以不固定,可以充满问题。 图:Chart 或者 Diagram 是将基本固化有一定规律的流程进行显性化和书面化,从而有利于传播与沉淀、流程重组参考。流程图即一种具有“明确逻辑化”的“图解表达”,而...
Swimlane diagrams vs. flowcharts The basic presentation of a swimlane diagram looks very similar to a standard flowchart. Both often use the same symbols and templates. But there’s a key difference. Flowchartsare most often used to map out a single process. Swimlane diagrams are more focuse...
Simplicity:Flowcharting isn’t like creating wireframes or prototypes. It’s a much simpler process of generally linking shapes and processes, therefore you want something with a simple interface. A lot of flowchart software is designed for more than just creating flowcharts (such as project manage...

Diamonds:These signify decisions. Just like in a flow chart, diamonds contain a question, which leads to a ‘yes or no’ decision you must answer to progress. Arrows:These connect the shapes. Follow the arrows to the next step. Circle:Circles act as connectors; they’re used when the rea...
Related Forms of the Process Flow Diagram Block Flow Chart (BFD) BFDs can also be used to simplify and decompose process flow systems. Moreover, such diagrams are the simplest form of the industrial flow chart and are usually considered as the first step to complete a process flow diagram...
Activity Diagram vs State Machine Diagram Related Links UML State machine diagram and activity diagram are both behavioral diagrams but have different emphases. Activity diagram is flow of functions without trigger (event) mechanism, state machine is consist of triggered states. Example: State diagrams...
