CONTEXT
Arden Syntax is a Health Level Seven (HL7) standard that can be used to encode computable knowledge. However, dissemination of knowledge is hampered by lack of standard database linkages in Arden knowledge bases (KB). Moreover, the HL7 Reference Information Model (RIM) is object-oriented and hence incompatible with the current Arden data model. Also, significant investment has been made in Arden KBs that would be lost if a backward-incompatible data model were adopted.
OBJECTIVE
To define a data model that standardizes database linkages and provides object-oriented features while maintaining backward compatibility.
ANALYSIS
We identified the objects of the RIM that could be used as a schema for standard database queries. We propose extensions to Arden to accommodate this model, including the manipulation of objects.
CONCLUSION
A data model that standardizes database linkages and introduces object-oriented constructs will facilitate knowledge transfer without violation of backward compatibility in the Arden Syntax.
背景
阿登语法是一种健康级别七（HL7）标准，可用于对可计算知识进行编码。然而，阿登知识库（KB）中缺乏标准数据库链接阻碍了知识传播。此外，HL7参考信息模型（RIM）是面向对象的，因此与当前的阿登数据模型不兼容。而且，如果采用向后不兼容的数据模型，在阿登知识库中已投入的大量资金将会损失。
目的
定义一种数据模型，该模型能使数据库链接标准化，并在保持向后兼容性的同时提供面向对象的特性。
分析
我们确定了RIM中可作为标准数据库查询模式的对象。我们提议对阿登进行扩展以适应此模型，包括对象的操作。
结论
一种使数据库链接标准化并引入面向对象结构的数据模型将有助于知识转移，同时不会违反阿登语法中的向后兼容性。
