| 摘要: |
| 面向对象的数据库管理系统（ＯＯＤＢＭＳ）通常都具备自身的查询语言，它以交互的方式供用户进行数据定义与数据操纵．除此之外，它还必须为程序员提供可在Ｃ、ＦＯＲＴＲＡＮ、ＰＡＳＣＡＬ等高级语言里嵌入使用查询语言的宿主语言接口．本文首先介绍这样一种Ｃ宿主语言接口Ｃ—ＯＳＤＬ，而后重点讨论它的实现技术，尤其是将Ｃ—ＯＳＤＬ命令转换成ＳＱＬ语句的翻译算法以及使用ＳＱＬ实现支持导航式查找的指针层次管理方法．文中讨论的Ｃ—ＯＳＤＬ实现技术以及最初的接口设计是面向对象的数据库技术的深入探讨． |

| Abstract: |
| An Object Oriented Database Management System (OODBMS) provides a query language that allows end users to define and manipulate database interactively. Besides, it must have host language interfaces for embedding query statements in C, FORTRAN, PASCAL or other languages. This paper presents the implementation of such ahost language interface -C-OSDL. In particular, the authors focus on the algorithms to translate C-OSDL commands into SoL statements and a method to manage cursor hierarchy for navigational re |
