I just joined my company, we are in Healthcare... I wanted to inquire on this issue.
We have 3 databases, One is our In house DB, 2nd one is a clearing House and 3rd one is our 3rd vendor.
We have a in house report with our Inhouse DB as a datasource which gives us financial data quaterly. on the other 2 DB`s we only get results in Excel and we cant query the other 2 DB`s...
What I need to do is do a cross comparision of data to figure out amount discrepancies... in all 3 datasets...
Is there a technique or what are the best practises on a high level .. I am trying to create a process on our side which will do the comparisons and publish a exact or a near exact match with a 2% variance.
Here`s what I had in mind..
Inhouse DB take the all 3 datasets and ETL into a Table which will House data from 3 data sources and then do the analysis?
Can someone help me out?
