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 text box code TextBox code element could modify the underlying data value. ref http msdn.microsoft.com en us library ms752347.aspx what is data binding What is data binding? ref See also XML data binding UI data binding References references Categories DEFAULTSORT Data Binding Category Data management Interwikies ja pl Data Binding pt Liga o de dados ... more details

Unreferenced date February 2009 A data island is a data store , such as on a Personal digital assistant PDA or other computing device , that has non existent or limited external connectivity. This limits the ability of the user to synchronize with or copy the data to other devices. Though new data can be added to the system, the ability to move that data elsewhere is impractical or impossible .Data islands, in general, contain a very huge set of data relative to its small physical space that it occupies. The connectivity here does not necessarily imply a hardware interface. For example, it may be a result of poorly written system interface software. A data island is a subset of entities that are connected to each other via relationships, but that are independent of other entities within the same data store.
