The analysis of clinical data collected over time can provide important insight into the health care process. Unfortunately, much of the electronic clinical data that exists today is stored in legacy systems, making it difficult to access and share the information. An approach is needed to improve the accessibility of electronic data stored in legacy system databases. In this study, a legacy database is converted into a relational format in the personal computer environment. The impact of such a conversion on query performance is evaluated, and issues that need to be considered when converting a legacy system database are identified.
对一段时间内收集的临床数据进行分析，可以为医疗保健过程提供重要的见解。不幸的是，当今存在的许多电子临床数据都存储在旧系统中，这使得访问和共享这些信息变得困难。需要一种方法来提高存储在旧系统数据库中的电子数据的可访问性。在本研究中，在个人计算机环境中将一个旧数据库转换为关系格式。评估这种转换对查询性能的影响，并确定在转换旧系统数据库时需要考虑的问题。
