【摘要】 论文设计了一个交易中间件模型,该模型由通讯协议和监控进程组成。该模型采用了多线程技术,具有并发处理能力;分布式交易采用两阶段提交协议、直接交易和交易冲正共同处理的方法、主从数据库策略,以保证交易完整性。在此基础上,开发了一个实际系统—银行ATM自动取款机售票系统,运用交易中间件,处理客户端请求的分布式交易。更多还原

【Abstract】 In this paper a transaction middleware model is designed,which is com po sed of communication protocol and monitor process.This model,employing multi-thread technique,has the ability of paralleling processing.To assure the in-t egrity of transaction,distributed transaction adopt such methods as two-phas e commit protocol,the method of direct transaction with correcting later,the s trategy of main-subordinate database.An application of ATM(Automatic Teller M a-chine)ticket selling is developed using transcation middleware.更多还原
