I'm quite new to SharePoint with an SQL background. Here are threequestion from a SQL point of view:1) Is there a way to use something like SQL transaction in SharePoint?2) How can we define / handle a unicity constraint in SharePoint?3) How can we handle concurrent update?
The only possible answer to your excellent questions is, "Use theSharePoint API" which uses transactions but isn't itselftransactionable. What I mean is that we cannot easily say, do thesethree calls and if one fails, rollback.
