摘要
现在有几个基于CODASYL规范的数据库管理系统1,2;这些包括UNIVAC的DMS 11003, DIGITAL EQUIPMENT的DBMS-104, Cullinane的IDMS5，以及在某种程度上Burroughs的B6700 DMS6。由于CODASYL规范尚未最终确定，并且由于所提议的标准的许多重要特性仍然是“实现者定义的”，因此这些特定的系统在许多方面都有所不同。但是，它们的基本数据结构功能仍然相似。本文的目的是概述使用CODASYL类系统时的一些数据库设计注意事项，并强调与其他类型系统的区别。
There are now several data base management systems which are based on the proposed CODASYL specifications1, 2; these include UNIVAC's DMS 11003, DIGITAL EQUIPMENT's DBMS-104, Cullinane's IDMS5, and to some degree Burroughs' B6700 DMS6. Since the CODASYL specifications are still not yet finalized, and since many important features of the proposed standard are left as "implementor defined", these particular systems all differ in a number of respects. However, their basic data structuring capabilities remain similar. The purpose of this paper is to outline some data base design considerations when using the CODASYL class systems, and to highlight differences with other types of systems.
