TransFER is a formal model designed to facilitate the sharing of decision-support applications across institutions with heterogeneous clinical databases. The TransFER model provides a mechanism to automatically customize database queries based on a reference schema of clinical data and an encoded set of database mappings. In this paper, we describe the elements of the TransFER model and we present the results of a formal evaluation we conducted to assess the utility and generality of the model. The results suggest that the TransFER has significant potential for automating query translation and facilitating application sharing, but that further work on the representation of temporal semantics, on the modeling of missing data, and on the optimization of complex queries is required.
TransFER是一个正式模型，旨在促进跨机构共享具有异构临床数据库的决策支持应用程序。TransFER模型提供了一种机制，可根据临床数据的参考模式和一组编码的数据库映射自动定制数据库查询。在本文中，我们描述了TransFER模型的元素，并展示了我们为评估该模型的实用性和通用性而进行的正式评估结果。结果表明，TransFER在自动查询翻译和促进应用程序共享方面具有巨大潜力，但在时间语义表示、缺失数据建模和复杂查询优化方面还需要进一步开展工作。
