csv

I have a transaction log file in CSV format that I want use to run statistics. The log has the following fields:

date:  Time/date stamp
salesperson:  The username of the person who closed the sale
promo:  sum total of items in the sale that were promotions.
amount:  grand total of the sale

I'd like to get the following statistics:

salesperson:  The username of the salesperson being analyzed.
minAmount:  The smallest grand total of this salesperson's transaction.
avgAmount:  The mean grand total..
maxAmount:  The largest grand total..
minPromo:  The smallest promo amount by the salesperson.
avgPromo:  The mean promo amount...

I'm tempted to build a database structure, import this file, write SQL, and pull out the stats. I don't need anything more from this data than these stats. Is there an easier way? I'm hoping some bash script could make this easy.
