Abstract: Methods and apparatus for supporting an additional data source in a system adapted for processing data from one or more data sources are disclosed. A design-time driver for the additional data source is obtained, where the design-time driver supports the definition of data including one or more fields of the additional data source to retrieve from the additional data source. In addition, a run-time driver for the additional data source is obtained, where the run-time driver supports retrieval of data corresponding to the one or more fields from the additional data source and where the run-time driver has a second application programming interface. The design-time driver is executed via a first application programming interface, where the first application programming interface enables definition of the data including the one or more fields to be retrieved from the additional data source.
