本文介绍核工业环境数据库系统。该系统包括九个关系型数据库,共48个关系。在每个库中定义了若干统计实体,用实体属性反应所关心的统计项目和实体间的联系。该系统建立在 Micro-VAXⅡ小型机上,使用该机提供的 RDB/VMS 关系型数据管理软件和 CDD 公共数据字典。管理应用程序用 FORTRAN 语言编写,采用模块化程序设计,全面使用屏幕管理和窗口技术,提供了十分友好的用户界面。该系统可以以全屏幕的方式,为用户实现数据输入(文件方式和键盘方式)、与/或检索、修改和删除等多种功能。系统还提供了21种专用统计报表,并具有报表自动生成功能。
This article describes the nuclear industrial environment database system. The system includes nine relational databases for a total of 48 relationships. A number of statistical entities are defined in each library, with entity attributes reflecting the statistical items of interest and the relationships among the entities. The system is built on the Micro-VAX II minicomputer and uses the RDB / VMS relational data management software and CDD common data dictionary provided by the aircraft. Management applications written in FORTRAN language, using modular programming, full use of screen management and window technology, provides a very friendly user interface. The system can provide users with data input (file mode and keyboard mode) and / or retrieve, modify and delete multiple functions in full screen mode. The system also provides 21 kinds of special statistical reports, and automatic report generation capabilities.
