This paper describes a data-base system for the maintenance of cumulative clinical data. A unique aspect of this data base is its ability dynamically to alter its two-level format to create an alternative three-level hierarchical structure in order to optimize retrieval efficiency. The relative advantages of these two types of data-base structures are discussed and examples of their use in clinical resrarch are presented.
本文描述了一个用于维护累积临床数据的数据库系统。该数据库的一个独特之处在于它能够动态改变其两级格式,以创建一种可供选择的三级层次结构,从而优化检索效率。文中讨论了这两种数据库结构的相对优势,并给出了它们在临床研究中的应用示例。
