分布式数据库的通用交互环境的设计和实现

针对DIS体系仿真的要求，结合计算机数据库技术的研究现状，选择分布式数据库系统，同时将解决其分布处理问题，实现DIS体系仿真的分布式数据库的实时交互功能，建立一个这样的通用交互环境，用户可以对本地或异地数据库进行操作，包括创建、查询、修改、删除等操作，不需要用户了解太多的具体数据库产品和软件开发工具。对数据库进行了修改以后，任何站点的用户都可以实时地看到数据库修改以后的情况。从而为用户提供了灵活、方便的对分布数据库的操作手段。

Design and Realization of a Universal Interactive Environment Based on Distributed Database

Aiming at the requirements of the distributed database system simulation and the development of computer technology, the present paper chooses the distributed database system,to solve distributed disposal. In order to realize the real-time interactive function, we establish a universal and interactive environment, where users can operate local and remote database, including creating, querying, modifying and deleting. When operating database in this universal environment, users needn't know about too much database product and software develop tools. After modifying this background database, users anywhere can see the modified data immediately. Therefore, this environment supply a flexible and convenient method of operating distributed database for users.
