How do you verify that data from multiple sources went through the ETL process and into the target Big Data store or Data Warehouse correctly?
Your project pulls data from various sources, including flat files, Excel, mainframe, and databases from different vendors. You need to retrieve data from these different platforms and then verify that the transformations of your ETL process have been performed correctly. You know you can code this, but the effort is daunting. What can you do?
