| 摘 要： | 多年积累的电子病历是一项重要的不可再生资源，对其数据的有效处理、利用是一项非常必要和有意义的工作。本文研究了电子病历数据前期处理的相关技术，涉及从电子文档资料到基础数据库的转换，对存入数据库的数据实施数据清理和数据变换等。通过数据预处理可以消除数据中的噪声、不完整和不一致性，实现数据的规范化和有效压缩，从而形成高质量的数据，可使数据的再处理（统计、数学建模、数据挖掘等）更加有效。

| Abstract: | The computer-based patient record diabetes that accumulated by many years is not re-genesis, so the effective management and use are an important and meaningful work. In this paper, we study the pre-processing technologies of computer-based patient record data, which involve the electronic document converted into the recording of database, data cleaning, data transformation and data reduction. Based on the pre-processing technologies, we can solve the noise, the non-integrity and the inconsistency of data, so data can be classified and compressed. Finally, we can obtain high quality data, which is more effective on data processing. |
