Tutorial Data Flow Diagram Using Microsoft Visio

A data flow diagram (DFD) is a tool for functional analysis that shows the general flow of information through a system or program. Most companies are creating e-commerce businesses as part of a long-term strategy of viability. E-commerce professionals can use Visio 2000 to draw process and data flow diagrams that clarify how customers will navigate an e-commerce site and how that site can make purchasing quick, easy, secure and profitable. In this tutorial, you’ll view an existing top process data flow diagram, add a new data flow to the top-level process, import the new data flow to a detail page, and create a new detail page. Step 1: Start Microsoft Visio 2000 Professional Edition. When the Welcome to Microsoft Visio dialog box appears, double-click the Browse Existing Files option. Step 2: In the Open dialog box, navigate to X*:Program FilesVisioSamplesSoftware. In the list of sample drawings, select NeuCom DFD.vsd. Under Open, click Copy, and then click the Open button to open a copy of the sample diagram. Notice that the data flow diagram (DFD) model-drawing file includes the DFD Navigator, which opens by default docked on the left side of the screen. In addition, the Status window opens docked on the bottom right of the screen by default. Step 3: Take a moment to look at the DFD Navigator. The DFD Navigator helps you easily navigate between levels in a diagram. In addition, you can use the DFD Navigator to add, delete and rename data flow diagram elements.
