A transaction is a collection of operations on the physical and abstract application state.
ACID
Atomicity. A transaction's changes to the state are atomic: either all happen or none happen. These changes include database changes, messages, and actions on transducers.
Consistency. A transaction is a correct transformation of the state. The actions taken as a group do not violate any of the integrity constrains associated with the state. This requires that the transaction be a correct program.
Isolation. Even though transactions execute concurrently, it appears to each transaction, T, that others executed either before T or after T, but not both.
Durability. Once a transaction completes successfully(commits), its changes to the state survive failures. (查看原文)
Christian wedding ceremony is a two-phase commit protocol:
it has a voting phase, in which all participants prepare to commit, followed by a second commit phase, in which they execute the commit.
A distinguished process acts much as the minister, coordinating the commit.
The transaction concept is the computer equivalent to contract law. If nothing ever goes wrong, contracts are just overhead. But if something doesn't quite work,the contract specifies how to clean up the situation. (查看原文)

译的很差，原版书还行，学数据库的不妨一读

原谅我暂时段位不够无法吸收此书的精髓；可能成书太早，对乐观并发这块涉及太少，作者甚至称“乐观”是对这个名字的羞辱；感兴趣的2PC优化也一带而过；原本想有一个overview也落空了

感觉比较晦涩，可能是层次不够吧

研究生期间读的书，真的对数据库事务讲的很清晰。Jim Gray，实至名归

不知道是我自身水平问题还是什么，整本书读起来极端的晦涩难懂；生产中的数据库好像也没有这么难啊，mysql的实现也不是不可理解啊。 这本书的最大贡献其实就是让我们明白在各个层面上存在的事务特性=原子特性，其他以我目前的水平，确实获取不到更多......
