In [[computer science]], '''Algorithms for Recovery and Isolation Exploiting Semantics''', or '''ARIES''', is a recovery [[algorithm]] designed to work with a [[no-force]], steal database approach; it is used by [[IBM Db2]], [[Microsoft SQL Server]] and many other [[database system]]s.<ref>{{cite journal|last1=Mohan |first1=C.|last2=Haderle |first2=Donald|last3=Lindsay|first3=Bruce|last4=Pirahesh|first4=Hamid|last5=Schwarz|first5=Peter|title=ARIES: A Transaction Recovery Method Supporting Fine-Granularity Locking and Partial Rollbacks Using Write-Ahead Logging|journal=ACM Transactions on Database Systems|date=March 1992|volume=17|issue=1|pages=94–162|doi=10.1145/128765.128770|doi-access=free}}</ref> [[IBM Fellow]] Dr. [[C.
