基于PL/SQL技术读取MARC元数据的设计与实现

The Design and Achievement of MARC Metadata Based on the Technology of PL/SQL to Reading

提出一种基于PL/SQL技术,针对Oracle数据库设计一个读取MARC元数据的存储函数,通过在SQL查询语句中直接调用该函数,实现对MARC元数据中著录项数据进行有效读取的一种方法。

This article presents a method based on PL/SQL technology which designs a storage function to read MARC meta- data aiming at Oracle database design, transfers directly this function from the SQL query, and effectively reads de- scriptive elements of MARC metadata.
