Our three years of experience in the routine use of a relational database for patient admissions is discussed. Following a brief summary of the principles and structures of the patient database, the problems of relational data manipulation languages (DML) and query languages are discussed in more detail. Experience with the physical representation of the data base is discussed. Our experience shows that a relational database, due to its structural clarity, offers clear advantages: data independence from user applications is achieved with a relational DML. The descriptive query language has end user acceptance problems. Possible reasons for these acceptance problems are analysed in more detail.
本文讨论了我们在日常使用关系数据库进行患者入院登记方面的三年经验。在简要总结患者数据库的原理和结构之后，将更详细地讨论关系数据操作语言（DML）和查询语言的问题。还将讨论数据库物理表示方面的经验。我们的经验表明，关系数据库由于其结构清晰，具有明显优势：通过关系DML可实现数据与用户应用程序的独立性。描述性查询语言存在终端用户接受度方面的问题。将更详细地分析这些接受度问题的可能原因。
