一种用于数据库数据集成的脚本语言

A Script Language for Data Integration in Database

Qingguo Zheng

摘要:

本文设计了一种脚本语言,通过计算公式将原始数据转换为目标数据。脚本语言可以翻译成相应的SQL语言,计算最终由第一类动态SQL实现。脚本语言对数据库中的表进行插入、更新、删除、并、交、减等操作,脚本语言通过文本文件编辑,可以方便地修改文本文件中的计算公式,以应对计算公式发生变化的情况。所以你只需要修改脚本语言的文本,而不需要改变已经编译的程序。

英文摘要:

A Script Language in this paper is designed to transform the original data into the target data by the computing formula. The Script Language can be translated into the corresponding SQL Language, and the computation is finally implemented by the first type of dynamic SQL. The Script Language has the operations of insert, update, delete, union, intersect, and minus for the table in the database.The Script Language is edited by a text file and you can easily modify the computing formula in the text file to deal with the situations when the computing formula have been changed. So you only need modify the text of the script language, but needn't change the programs that have complied.
