摘要： 微机分布式数据管理系统MNDB是在关系数据系统dBASEⅡ的基础上设计的,它提供透明的远程数据定义和操纵设施,分布式事务管理和数据一致性控制。系统由四部分组成:结点数据库系统dBASEⅡ执行本地事务;分布数据控制管理模块协调多结点事务的实现;网络字典系统NDS提供系统处理支持信息;网络通信系统提供消息传输服务。

Abstract: The design of microcomputer distributed database management system MNDB presented is based on the relational database system dBASE Ⅱ . The system provides transparent remote data definition and operation facilities, distributed transaction management and data consistency control. The system consists of four parts: site database management system dBASE *, distributed data control and management moduler, network dictionary system (NDS) and the network communication system.
