ACID rule for transaction

博客介绍了事务的ACID规则。原子性指事务是一个工作单元,不依赖前后事务;一致性表示数据要么提交要么回滚,无中间状态;隔离性意味着事务看不到当前事务的中间结果;持久性是数据提交后即使系统崩溃也会持久保存。

ACID rule for transaction:

Atomic: it is one unit of work and doesnot dependent on previous and following transactions

Consistent: data is either commited or roll back, no "in-between" case where something has been updated and something hasn't

Isolated: no transaction sees the intermediate resules of the current transaction

Durable: the values persist if the data had been committed even if the system crashes right after.
