Abstract: This paper analyzes the process about the integration of the C-Omega language and the query language, points out the merit of using inquiry operator in the integration, and proposes a solution about impedance mismatch on operating the data set based on the C-Omega and query language on basis of this. The solution can solve the contradiction about the differences of the programming style and the data type in developing the software between the query language and the host language, and it also can discover errors earlier in the database.

Key words: impedance mismatch, query language, C-Omega language, data set

摘要： 分析C-Omega语言和查询语言的集成过程，指出集成中使用查询运算符的优点，提出C-Omega语言和查询语言在操纵数据集时阻抗不匹配的解决方案。该方案解决了查询语言和宿主语言在软件开发中编程风范不同且数据类型相异的问题，并能及时发现数据库中的错误。
