Creating a Link (Evaluation Guide)

Go Up to Session 11: Create Links and Usages

We are going to link a table we imported from the ER/Studio sample model to the “Check Order” task we created in our Business Process diagram.

1 Click the Order Picking tab in the Diagram View to display the diagram you created.

2 Right-click the task labeled Check Order, select Create Link from the shortcut menu and the Create Link Wizard opens.

3 In the Target elements list box expand the Entities subnode in the External Data Objects node and select Customers.

4 We will specify the following details for a new link in the Create Link dialog:

Name	Name the link Check Order Customer Link
Type	Select Usage. When you select this option you can model whether database records are to be created, read, updated, or deleted. When this option is selected, all created links are labeled “usage”
Verb Phrase	Type a verb phrase that describes the relationship from the perspective of the target. Enter the text CUSTOMER validates ORDER.
Inverse Verb Phrase	Type an inverse phrase that describes the relationship from the perspective of the element to be linked to. Enter the text ORDER is validated by CUSTOMER.
Usage	Select Read. This selection doesn’t actually read a database record but “models” the fact that a record could be read from the database.
Documentation	Enter any descriptive text you wish here.

5 Click OK and the Create Wizard dialog closes.

6 Right-click in the diagram and select Connections>Show>Links from the shortcut menu. The link you just created is then displayed in the Order Picking diagram.
