STEP $1$: Create a Block Diagram $(15$ points$)$

The block diagram should show the boundaries of the ED information system.

On the File menu, point to New, point to General, and then click Basic Diagram and then Choose Create.

From Basic Shapes, drag shapes onto the drawing page.

Resize and rotate shapes as necessary.

Resize

Click a shape to select it and do one of the following:

If the shape has selection handles, drag one until the shape is the size you want. To resize the shape proportionally, drag a corner handle.

If the shape has endpoints, drag an endpoint to the length you want.

Rotate

Select the shape, and then drag the rotation handle.

You will use these shapes to create a diagram for the ED system components.

STEP $2$: Create Components and Relationships $(15$ points$)$

Add the components of the ED information system and their relationships.

To create components and relationships, drag appropriate shapes to your diagram to represent components and relationships. You can associate multiple shapes with the same component.

To add text to a shape, select the shape and then type.

STEP $3$: Create Systems Inputs, Outputs, and Interfaces $(20$ points$)$

Use system inputs, outputs, and interfaces with systems outside the ED information system.

To create inputs, outputs and interfaces, drag appropriate shapes to your components and relationships.
