摘要
为解决异构数据库之间的数据交换问题，实现对工程数据和事务数据的一体化管理，本文提出了工程数据库管理系统ＥＤＬ和关系数据库管理系统ＯＲＡＣＬＥ集成的一种方法，使得用户可以在ＯＲＡＣＬＥ上直接操纵ＥＤＬ中的数据。
To solve the communication problem among multidatabases, and implement the uniform management of engineering data and business data, a method of interconnection between EDBMS EDL and RDBMS ORACLE is presented, which realizes their converting interface. Thus users of ORACLE can directly manipulate data that is stored in EDL. Also operating form of structural and non structural data is uniformed with SQL.
