Atomic operations allow an all-or-nothing approach to database updates. Grouping operations together provides for both business unit cohesiveness, as well as performance. Multiple files take part within a single transaction. Should any operation within the transaction fail, this entire sequence can be immediately aborted. Compare this to maintaining individual file updates under your own control.

To enhance the all-or-nothing atomic operation, complete savepoint and rollback features allow you to quickly move within a transaction as conditions change. Errors can be handled and operations adjusted without completely starting over.

In addition, FairCom DB offers extremely fine grained locking mechanisms both within and between transactions. The ability to keep locks from before a transaction begins, and maintain locks after a transaction commits gives FairCom DB developers control unavailable in most other database technologies. This yields a key advantage to high performance and acutely tuned applications.
