医学数据管理系统MDMS及其在医学和化学上的一些应用

医学数据管理系统MDMS采用关系方法建立数据模型。MDMS第一版首先在CBM4000上实现,后移植蓟CBM8000及TRS—80上,采用BAS1C语言编写,用于定长记录。MDMS第二版在小型机PDP11/44上实现,它允许变长记录;由于使用了倒排文件,因此2加快了多码检素时的查找速度。同时也由于编译成机器语言程序。从而提高了运行速度。MDMS具有插入、检索、修改、删除,显示键目录、排序、数据转换计算及调用应用程序等九项功能,并兼顾了医学及化学应用方面一些特点。利用MDMS,建立了几个小型专用的科研数据库:黄疸数据库、胃脘痛数据库、心肌梗塞数据库、甲亢数据库、以及化学药品数据库。利用黄疸及胃脘痛数据库,完成了《黄疸会诊程序JDD1及JDD2》及《电子计算机模拟名老中医梁乃津的胃脘痛经验程序UAP·CAD》两项科研项日。MDMS-2已移植至IBM-PC及APPLE II 机上。

MEDICAL DATA MANAGEMENT SYSTEM (MDMS) AND ITS APPLICATION IN MEDICINE AND CHEMISTRY

MDMS is a data management system designed especially for medical and chemical application. In addition to the usual data manipultation functions (insettring, retrieval, update and sorting), many application functions such as statistics, calculation, data coavertion, link to other programs etc., were also provided. Retrieval function was expanded to fulfill multi-keys and multi-criteria Boolean search. A new data type-triple value-was developed to store numerous clinical symptoms and signs. Using MDMS, several medical and chemical data bases had been established on micro or minicomputers. Four research projects are carried on smoothly using these data bases. MDMS fulfilled most of their requirements.
