摘要
随着ＣＡＤ／ＣＡＭ等工程应用的逐步深入，对具有分布式管理功能的工程数据库管理系统的需求日益迫切。为此，在我室自行研制的单用户工程数据库核心管理系统ＥＤＢＭＳ／２的基础上，我们设计并实现了一个分布式工程数据库管理系统——ｄＥＤＢＭＳ。ｄＥＤＢＭＳ运行在ＳＵＮＴＣＰ／ＩＰ网络环境，基于作者提出的扩展客户／服务器体系结构，针对工程应用之特点，提供远程数据库访问和检出／检入两种操作模式，支持多服务器的自动寻址，并具备其它一些必要的分布式控制功能。
With the deeper development of CAD/CAM application,engineering DBMS with distributed function are urgently needed.So,on the basis of EDBMS/2,which is a single user engineering database management system developed by our Lab.,we designed and implemented the dEDBMS system a distributed Engineering DataBase Management System.dEDBMS is based on the extended client/server architecture presented by the author,and runs under the SUN TCP/IP network environment.In views of characteristics of engineering application,dEDBMS provides two kinds of distributed service mode:RDA(Remote Database Access) and check out/check in,supports automatic server allocation,and possesses necessary distributed control functions.
