To avoid delays during development, simulated data should be used when a data source is unavailable.

For example, while your team is building a weather widget, the team members building the UI want to see how their design works with data in place before the team members working on the connector to the data provider have finished their work.

1. Create sample data for your application. For more information, refer to Creating a data type in

   You can provide the sample data from a lookup, a data transform, or a load activity. The sample data should include values to populate all the properties that the page, section, or other component referencing the data page requires.

2. In Dev Studio, in the Records Explorer, expand the Data Model record.

3. Click Data Page.

4. Click the data page of interest that the application will reference.

5. In the Definition tab, in the Data Sources section, select the Simulate data source check box.

6. In the System name field, enter or select the name of the system to use for simulated data.

7. Click Save.
