To use Eclipse Data Binding, the following path will help you understand the basics:

• Bind a String property to a Text
• Bind an Array or List to a JFace Viewer

Once you understand the basics, you need to know about:

• Binding 1-M relationships (ie: Customer –> Order –> LineItem)
• What is an IObservableValue anyway? How/when do I create one?
• Field-level validation
• Business rule validation

Really advanced stuff:

• Binding Non-UI Things
