摘要: 系统地论述了数据库的工程界面、数据库管理系统、程序设计语言三者之间的层次关系。以STEP标准的SDAI(StandardDataAccesslnterfaee)作为数据库工程界面的具体例子,详细地论述了它向ODBMS及RDBMS的映射。对于向RDBMS的映射,提出了“知子女联系”向“知子女联系”的映射策略,为简化映射算法、提高系统效率提供了一种选择。

Abstract: There exists a hierarchical relationship among engineering interfaces, database man-agement systems and programming languages.M apping from SDAI of STEP, as an example of engineering interfaces of databases,to OD B M S or RDBM S is described,A mapping strategy known as “ways to children”to“ways to children”is presented.This strategy provides an option for simplification of the mapping algorithm and improvement of system performanee.

Key words: engineering, data base, programming, interfaces, data base mangement systems, computer aided design
