Many organizations use SAS for house holding database marketing.
Merge/Purge the Marketing database by Name and Address.  Creating a  SAS
dataset for modeling purpose after you have done a GROUP1 processing. SAS provides the functionality to match with your customer info file in sizes as large as of 220 million records or more.  There are companies that will handle this for you. It handles addresses and names very nicely. It is strongly recommended that you do not try to do your merge/purge in SAS. The GROUP1 merge/purge has
extensive rules and scoring algorithims which you would be hard pressed to
approximate in SAS and your programs would probably run very much longer.
