Atomic transactoions vs Compensation

[Ginny]

Hi,

If we cannot implement atomic transactions we need to implement compensating
methods and processes ?? Why?? Does compensating here mean simple error
handling and a manual mechanism to roll back the state of a process?? I read
abt compensation in BizTalk, is it simialr ??

To undo what has been done so far.

Yes. Note that compensation has a lot more facets than a TX rollback. A sent
E-mail for example cannot be simply rolled back. You can try to recall the
message, or you can send another E-mail that tells the recipient to ignore
the original message.
