摘　　要：在数据库中使用事务功能,就可以把数据遭破坏的可能性降到最低。然而,事务处理需要耗费大量的计算机资源,它必然会引起系统性能的降低,甚至由于多个事务的不合理设计造成冲突而产生死锁现象,这是一名数据开发者所不愿意面对但却必须解决的重要问题,该文描述了通过优化事务的方法来避免死锁的发生。Using the function of transaction in database can reduce the possibility of data being destroyed to the minimum. However, transaction will expend computer resources, which will inevitably impair of system function. And lock may occur due to many unreasonable transaction designs. It is an important problem data developer isn＂ t willing to face but has to solve. This paper elaborates how to avoid lock by transaction optimization.
