Nice Explanation very clear

[@AmalPeter1984]

can you pls post video for the validations done in each layers ,I mean
Validations for source to landiing ,
Validations for landing to Staging ,
Validations for staging to Target datawarehouse .

[@prajakta887]

I want know here we use NVL function to replace null value with default value so does default value reflect to the original table in place of null value

[@srtechnologiesravindraredd5303]

Select command never replaces any value in the original table. If you use "update" command it will replace it.

Sirjee what is the answer of last questions ? Oracle = 10Millions records Snowflake = 10 Millions Records how many ways that we used to compare these massive records?????******* 1. Read data from both Databases in the pandas data frame and then compare the data frame? any performance issue?

[@srtechnologiesravindraredd5303]

Yes Ji, f you have Spark/Pyspark in your environment, utilize Pyspark/spark,it run effectively and process the data very faster compare to pandas..behind the reason is it's distributed computing..
