Data binding

Data binding is a general technique that binds two data/information sources together and maintains synchronization of data. This is usually done with two data/information sources with different types as in XML data binding. However, in UI data binding, data and information objects of the same type are bound together (e.g. Java UI elements to Java objects).

If the binding has been made in the proper manner, then, each data change is reflected automatically by the elements that are bound to the data. The term data binding is also used in case where an outer representation of data in an element changes, and the underlying data is automatically updated to reflect this change. As an example, a change in a TextBox element could modify the underlying data value.
