/>一、引言<br /><br />B/S构架的应用越来越普及，但由于它有别于C/S构架的特殊性，并发控制始终没能得到很好的解决，如售票系统经常会出现同一张火车票出售多次的现象。典型的案例如下：<br /><br />例如若有两个客户端，A客户先读取了账户余额2000元，之后B客户也读取了账户余额2000元的数据，A客户提取了500元，对数据库作了变更，此时数据库中的余额为1500元，B客户也要提取1300元，根据其所取得的资料，2000-1300将为700余额，若此时再对数据库进行变更，最后的余额700元就会不正确，应当是200元，问题的出现是由于两个客户对同一条数据进行并发访问造成的。<br /><br />Web应用中并发控制的特殊性<br /><br />上述问题在C/S构架中可以通过长事务来实现，但Web应用是基于Internet网络环境的，其中的并发控制有其内在的特殊性[1]：<br /><br />（1）Web所基于的网络协议HTTP(Hyper Text Transfer Protocol)是一种无连接的协议，数据库服务器无法保存事务的状态信息；<br /><img src
