A system for generating an On-Demand reconfigurable Web application that provides create/read/update/delete-functionality on data managed in one or more external data sources. An XML-based definition is accessed to learn of desired create/read/update/delete-functionality in pre-defined form, graphical interfaces (GUIs) on functionality, non-typed definitions of data in the data sources, as well as data logic related to the data sources and the various relationships between these items. Upon request the definition is parsed and one of the GUIs is presented or some of the defined functionality is executed. An abstraction layer is used to obtain access to the data managed in the external data sources and On-Demand-Instantiation is applied to type the non-typed objects within the context of the definition of the functionality being executed. |
