Abstract

A computerized database system (DIASTU) has been developed for the storage and selective retrieval of the results of medical diagnostic studies. The system is being used to analyze the disease process and the efficacy and yield of selected diagnostic studies. The system runs on a DEC PDP-11/60 computer. It consists of three FORTRAN IV programs linked to a general-purpose assembly language database handler. One program, DSENT, interactively modifies the information in the database. The second, DSLIST, prints all or portions of the database. The third program, DSTAT, interactively assembles the parameters for selective searches of the database and executes them. A query language is used that allows the use of time and size specifications and Boolean operators in nested loops.

摘要

已开发出一种计算机化数据库系统（DIASTU），用于存储和选择性检索医学诊断研究结果。该系统正用于分析疾病过程以及所选诊断研究的疗效和产出。该系统运行于DEC PDP - 11/60计算机上。它由三个FORTRAN IV程序与一个通用汇编语言数据库处理器相连组成。一个程序DSENT可交互式修改数据库中的信息。第二个程序DSLIST可打印数据库的全部或部分内容。第三个程序DSTAT可交互式组装用于数据库选择性搜索的参数并执行这些搜索。所使用的查询语言允许在嵌套循环中使用时间和大小规范以及布尔运算符。
