To efficiently store and retrieve cardiac catheterization records, we have developed a computer-assisted database, which comprises a 16-bit microcomputer with dual floppy disk drives, a 20 MB random-access memory, hard disk drive, and a line printer. All programmings were accomplished using a relational database management system (R:base 5000, Microrim, Inc.). Data inquiry procedures could be performed with direct operational commands of the system as well as with preprogrammed command files, and final results of searches were printed out with a line printer. The major advantages of the present system described in this report include: (1) the relatively easy and rapid creation of the database, (2) ease of modification of the database structures even after the system design is finished, (3) operational commands in combination with conditional operator(s) are flexible and powerful enough to allow the end user to retrieve data based on various kinds of criteria, (4) a high-level programming language provided by the R:base automates a series of database procedures with relative ease, (5) relational capabilities of the database management system can enhance the possibility of reconstruction of a new data file from a single or several preexisting data files, and (6) the system can be realized at reasonable cost.
为了高效地存储和检索心导管检查记录，我们开发了一个计算机辅助数据库，它由一台带有双软盘驱动器的16位微型计算机、一个20MB的随机存取存储器、硬盘驱动器和一台行式打印机组成。所有编程工作均使用关系数据库管理系统（R:base 5000，Microrim公司）完成。数据查询程序既可以通过系统的直接操作命令执行，也可以通过预编程的命令文件执行，搜索的最终结果由行式打印机打印输出。本报告中描述的当前系统的主要优点包括：（1）相对容易且快速地创建数据库；（2）即使在系统设计完成后，也易于修改数据库结构；（3）与条件运算符结合的操作命令灵活且强大，足以让最终用户根据各种标准检索数据；（4）R:base提供的高级编程语言相对轻松地自动化了一系列数据库程序；（5）数据库管理系统的关系能力可以提高从单个或多个现有数据文件重建新数据文件的可能性；（6）该系统可以以合理的成本实现。
