Abstract

The present invention relates to an XML application framework (XAF). XAF applications are data driven such that all operations with the computer system are data focused. In addition, the components used in the XAF application are instantiated and connected according to how the data is displayed and what type of data is used. Applications within XAF comprise a user interface (UI) connector, an action module, and a data connector. UI connectors receive UI events and connect the UI event to an action module. The action module generates a standard format action from the UI event and sends it to the data connector. The data connector translates the standard format action into a data-specific action that changes data in a data store. A data connector then sends a standard format data representation corresponding to the changed data back to the UI connector to provide the changed data to the UI.
