Because of space I intentionally didn't point out that there are different isolation levels that are available. However, it is useful to point out that the transaction example I used doesn't work as given at all isolation levels. For the reader who is interested in these isolation levels here is a good post written by my co-worker Sheeri http://sheeri.com/content/isolation-%2526amp%3B-concurrency Let me point out one thing.

But at performance pages, they compare InnoDB to 'Other databases' and follow a comparative grid results granting InnoDB a tenfold advantage over 'Others DB'. Yup I could not believe my eyes : 'Other DB'. You trigger my curiosity so I want to InnoDB home page and noticed that InnoDB is a subsidiary of Oracle.
