Just curious what are all the best practices in industry for error handling which includes generating the exact version of source format . So that end user can correct and reload it.
Also what is the best practices of validating data in oracle db after data load? Right now I am doing the count ,distinct to find different column values and spot checking the data format. Is there any opensource tool available for data validation?
What should I expect the output as per ETL work? Right now gathering stats and generating excel for missing records.
Please share some guidance on this...
Thanks...
