    摘要: 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. The data is then retrieved from the additional data source via the run-time driver using the second application programming interface.
