Connecting to live data
Production applications often use live data sources to display dynamic content. Live data, if available, is displayed when you run your application (F5). If you need to see data in objects on the artboard in order to style them, you can use sample data.
If you create your sample data to use the same schema as the live data that your production application uses, you can simultaneously bind sample data and live data to the same objects. Your sample data will be displayed on the artboard, and live data will be displayed when you run your application (F5).
