【摘要】 OLTP(On-Line Transaction Process)联机事务处理系统，是当今信息管理系统中应用极为普遍的信息处理模式，其三层体系结构为信息管理技术提供了诸多便利，但在开放式的计算机网络系统中，并且系统的运行要跨广域网，系统的安全问题是一个重大的研究课题。本人自1996年以来，一直从事联机事务处理(OLTP)系统的研究和开发，在系统体系结构，特别是系统的高可靠性、高可用性和高安全性等方面，做过比较深入的研究。目前，本人参与设计开发的OLTP系统，已经投入试点运行。在这一覆盖全国、跨广域网运行的系统中，本人主要承担了系统体系结构的设计及原型开发，对系统及数据库的安全性进行了严格的测试；主持并参与了系统授权、病毒防治、系统高可靠性、系统高可用性和系统容灾系统的设计。系统实施后，运行状况良好，发挥了巨大的经济效益和社会效益。由于此系统涉及面广，技术含量较高，限于篇幅，在论文的详细阐述中，还不够深入。更多还原

【Abstract】 I have been undertaking the study and development of OLTP system since 1996. Especially in architecture, high reliability, high availability and high security, I have done the research deeply. Recently, the OLTP system of which I took part in design and development has been run in some units. The system will be deployed all over the country and ran in wide area network. I mainly took charged with the design of the architecture and the development of prototype, and also had a detailed test to the security of the system and database. I led and participated the design of authorization, virus preventing, reliability, availability and disaster toleration. The system has been running very well since it was deployed. We have got a great economic and social benefit. Since the system has a wide use of technology and the paper has a limit to the words, I can’t have a detail dissertation更多还原
