摘要
分布式数据库管理系统的研制是当今数据库技术发展的重要方向。本文着重进行了管理系统的数据抗毁性和数据一致性设计,给出系统冗余设计和延迟更新方法;采用远程函数调用方式完成消息的发送,实现了结点间的数据通信。进一步采用数据字典实现了数据透明。经检验具有较好的效果。
Distributed Database Management System is one of the most important fields in the database technology. Data security and data inconsistency are discussed at first in this article. then abundant design and delayed update methods are proposed. Furthermore, data communication is realized by using farther function. At last data dictionary is improved to acquire data transparency and system security.
