Lab Steps
STEP 1: Create a Data Flow Diagram (10 points)
Create a data flow diagram, including external entities.
On the File menu, point to New, point to Software and Database, and then click Data Flow Diagram.
From Data Flow Diagram Shapes, drag an External interact or shape onto the drawing page to represent each external source or destination for data.
Drag more shapes onto the page to represent the processes, states, or entities involved in the data flow you are documenting.
Indicate the flow of data in your diagram with Center to center shapes and indicate data loops using Loop on center shapes.
STEP 2: Create Data Stores and Process
STEP 2: Create Data Stores and Processes (20 points)
Create all the components of data stores and processes.
From Data Flow Diagram Shapes, drag a Center to center shape onto the drawing page. Place it near the two shapes between which you want to show the flow of data.
To change the direction of the arrow, right click on the shape and adjust the arrows options in the pop-up menu.
Drag the endpoints of the Center to center shape to the connection points x at the center of each of the other shapes. The endpoints turn red to indicate that the shapes are connected.
To change the arrow curvature, drag the selection handle . To change the location of the ends of the arrows, drag a control handle .
STEP 3: Create Data Flows (20 points)
Add all the components of data flows based on the scenario.
