Creating an Include Relationship |
In this section you will create an include relationship between the following schemas provided in the include_redefine sub-folder of the SchemaAgentExamples\Tutorial folder:
| • | event_registration.xsd: This schema is structured to contain information about a participant who registers for a sporting event. Because these events have fees, a type for containing credit card information is also defined in this schema. |
| • | dvd_order.xsd: This schema is structured to contain order details for mail order DVDs, and customer shipping details. |
In the course of this example, you will create an Include relationship so that dvd_order.xsd includes types from event_registration.xsd, specifically those that store customer and credit card data.
To display schemas in a Design window:
| 1. | Select the menu option File | New, or click the New  icon in the Standard toolbar, or press Ctrl+N to open a new Design window. |
| 2. | In the Explorer window, select event_registration.xsd and dvd_order.xsd from the include_redefine folder and drag them into the Design window. |
Please note: To drag and drop more than one file at the same time, select the files first by clicking on the files while holding down the Ctrl key. Drag and drop a folder to put all the files it contains in the Design window.
To create an include relationship:
| 1. | Click on the small white triangle on the right side of the file box of event_registration.xsd and drag the connector line to the file box of dvd_order.xsd. |
| 2. | Release the mouse button over the word "includes". |
A green arrow that points from event_registration.xsd to dvd_order.xsd appears.
This arrow shows that an include relationship has been made between these schemas.
