摘　　要：随着大数据、云计算和云服务等新技术的兴起,并发分布式计算作为这些新技术的基础,扮演着越来越重要的角色.在分布式计算中,数据的一致性难以得到保证,而事务处理技术能够有效解决该问题.为了提升PAR平台在高可靠应用程序的使用范围,在其建模语言Apla中融入了并发分布式事务处理机制,使得Apla语言不仅支持分布式数据库事务,还支持分布式非数据库事务.该文对Apla语言并发分布式事务处理机制进行了深入地研究,并将其应用在学生管理系统、在线购物系统等实际应用场景中.With the emergence of new technologies such as big data,cloud computing,and cloud services,concurrent distributed computing is playing a more and more important role as the foundation of these new technologies.In distributed computing,data consistency is difficult to guarantee,and transaction processing technology can solve this problem effectively.In order to enhance the application of PAR platform in high reliable applications,the concurrent distributed processing mechanism has been integrated into its modeling language Apla,which Apla language supports distributed database transaction and non-distrubuted database transaction.The mechanism is deeply studied and used in constructing student management system and online shopping system.
