	ADF BC: Programmatic Data Source Mode


	By default, ADF BC provide data interchange with database by mean of JDBC calls.

	However, this default behavior can be changed because API clearly defines methods in every class, which implement data source functions. We need to override these methods in order to create our own data source processing.

	The WSDS solution goes right this way - we create extended BC classes with programmatic implementation of data source methods. All JDBC requests to database are replaced by requests to the web service data source.

	The solution is suitable for several latest versions of ADF or BC4J - since those where data source methods appear in Business Components API. For example, in our company we use production framework based on BC4J version from JDeveloper 9.0.3.
