In medical software development, the use of databases plays a central role. However, most of the databases have heterogeneous encoding and data models. To deal with these variations in the application code directly is error-prone and reduces the potential reuse of the produced software. Several approaches to overcome these limitations have been proposed in the medical database literature, which will be presented. We present a simple solution, based on a Java library, and a central Metadata description file in XML. This development approach presents several benefits in software design and development cycles, the main one being the simplicity in maintenance.
在医学软件开发中，数据库的使用起着核心作用。然而，大多数数据库具有异构编码和数据模型。直接在应用程序代码中处理这些差异容易出错，并且会降低所生成软件的潜在可重用性。医学数据库文献中已经提出了几种克服这些限制的方法，将在本文中进行介绍。我们提出了一个基于Java库和一个XML格式的中央元数据描述文件的简单解决方案。这种开发方法在软件设计和开发周期中具有几个优点，主要优点是维护简单。
