Not really: https://en.wikipedia.org/wiki/ACID https://en.wikipedia.org/wiki/ACID
He confuses ACID and isolation levels. Typical internet FUD.
- ak39 11y agoAgreed. Also, Microsoft SQL Server does support snapshot isolation. See: https://msdn.microsoft.com/en-us/library/tcbchxcb(v=vs.110).aspx https://msdn.microsoft.com/en-us/library/tcbchxcb(v=vs.110)....

- angelbob 11y agoThe link you give defines isolation like this: "The isolation property ensures that the concurrent execution of transactions results in a system state that would be obtained if transactions were executed serially, i.e., one after the other." That sounds awfully close to the definition of serializability he's using.
