Is there any

Answer 1

Yes you can find unaltered data through getOrigData() as pointed out by clockworkgeek but Magento has a build in function to compare and check if the data has been changed. The method is called dataHasChangedFor() and you have to pass the property that you want to check. It would look somthing like this.

$isChanged = $productData->dataHasChangedFor('description'); 
if ($isChanged) { 
// do somthing 
}

here the method dataHasChanged() will return boolean value based on whether the data was altered.
