摘要
文中首先分析了Ｃｌｉｅｎｔ／Ｓｅｒｖｅｒ模型中中间件（ｍｉｄｄｌｅｗａｒｅ）的应用背景．在此基础上，提出了适合工程领域的基于多层结构（ｍｕｌｔｉｔｉｅｒ）中间件ＥｄｂＣｌｉｅｎｔ，ＥｄｂＳｅｒｖｅｒ的设计方法，描述了它在分布式工程数据库管理系统ＤＥＤＢＭＳ／ｘ中的实现．最后，介绍它在“九五”国家科技攻关项目“集成化商业设计ＣＡＤ系统”中的应用．
The background of middleware in client/server model is introduced first and then a method of the middleware (EdbClient,EdbServer) design based on multitier is presented,which is suitable for the engineering field.The implementation of a middleware in DEDBMS/x by using this method and its application in “Integrated Merchandise Design CAD System” are also described in the paper.
