// ABC inc.'s  DB lib (closed source lib)
interface DatabaseItemInterface
{
	...
	int get(); // load the data from the DB into the object, return something
	...
}


// XYZ corp.'s finance framework (closed source lib)
interface PerchaseRequest
{
	...
	int get();	// return the PO number for this item
	...	
}
