Fellow Monks,

I'm involved in switching a client over to a new platform. Part of the platform change is a change of database platforms (from mainframe to SQL Server). I've been tasked with coming up with a data verification tool to make sure the data did not go corrupt in the move. I've selected Perl to do this task.

Essentially, I have 2 CSV files: One from the mainframe, and one from the SQL server. I need to compare these record by record, field by field, and note any differences. I started down the road of using the DBI interface with CSV files, but I'm not certain if this is the way to go. I have these options available to me:

I'm thinking it may be easier for me to use the CSV file as a driver as I am now, but use ODBC access to the SQL server to do the lookup / compares. Any thoughts would be appreciated. Thanks.
