Use Jim's article for a high-level overview only. It uses RDS for data passing. RDS is no longer recommended as it's full of security holes. Use XML between tiers.


>Thanks Craig. I guess that's the reason for which XML was invented; passing data in an explicit manner through tiers. Funny thing is that, if you have auto-links enabled and click on the tier word in this message you'd get to Jim's article published here on the UT. I guess that's the paper you mention.

>>>Could anyone here recommend a good book or docs on 3-tier development? I am mostly interested in methodology for passing data from presentation, thru mid-tier, to database for updating. Thanks.
