写的不错,补充一下: Isolation level 是ANSI SQL 的标准,不是SQL Server 的概念。每个 rdbms 实现 Isolation level 的方式都不一样,这也是 Oracle 比 SQL Server 设计上更优异的 一个地方。举个简单的例子,Oracle 的 Undo image的概念保证了 non-blocking read 没有 dirty read 的忧虑,所以根本不需要象 SQL Sever 那样为了提高 performance 牺牲 integrity。换句话说,同样的 transaction isolation level 下 (by default 都是 Read Committed), Oracle 不需要 SQL Server 那么多 Locking,所以 Oracle 在 performance 上比 SQL Server 有先天的优势。 前几天被老板逼着去 Redmond 上了MS SQLServer 两周课,认真做了 one on one 的比 较,不可否认,SQL Server 也有些相对的优点,不过在很多地方和 Oracl
There you go. Spark just show one typical mindset conflict between Oracle developers and SQL Server developers. SQL Server developers: We think 管理层的人不懂,听locking变色. locking is necessary and we can't live without it. Anyone who try to use "nolock hint" to improve performance will have to worry about Dirty Read (as "nolock hint" just changed the Isolation Level to Read Uncomitted) (Note: that mindset is actually true before SQL Server 2005 Yukon release.) Oracle developers: Oracle by design achiev
