ISO/IEC 13249:2003: 介绍了ISO/IEC 13249的全文部分（全部部分）；提供ISO/IEC 13249:2003所需的参考资料；定义特定于ISO/IEC 13249:2003的符号和约定；定义特定于ISO/IEC 13249:2003的概念；定义全文用户定义类型及其关联的例程。 ISO/IEC 13249:2003中定义的全文用户定义类型遵循以下内容。 全文用户定义类型是文本处理的通用类型。它解决了使用诸如单词、短语、邻近扩展、模糊扩展和基于同义词库的扩展等模式基于全文数据的方面搜索和检索信息的需求。它还解决了为文本识别设施和文本排序设施构建这种搜索模式的需要。全文用户-defined type不会直接或与其他全文数据类型组合重新定义数据库语言SQL。 ISO/IEC 13249:2003的实现可以存在于还支持信息和内容管理、决策支持、数据挖掘和数据仓库系统的环境中。 ISO/IEC 13249:2003的实现所涉及的应用领域包括但不限于图书馆、报纸、多媒体和科学研究应用。

ISO/IEC 13249:2003:

1. introduces the Full-Text part of ISO/IEC 13249 (all parts);
2. gives the references necessary for ISO/IEC 13249:2003;
3. defines notations and conventions specific to ISO/IEC 13249:2003;
4. defines concepts specific to ISO/IEC 13249:2003;
5. defines the full-text user-defined types and their associated routines.

The full-text user-defined types defined in ISO/IEC 13249:2003 adhere to the following.

• A full-text user-defined type is generic to text handling. It addresses the need to search and retrieve information based on aspects of full-text data using patterns such as words, phrases, proximity expansion, fuzzy expansion and thesaurus based expansions. It also addresses the need to construct such search patterns for text identification facilities and text ranking facilities.
• A full-text user-defined type does not redefine the database language SQL directly or in combination with another full-text data type.

An implementation of ISO/IEC 13249:2003 may exist in environments that also support information and content management, decision support, data mining and data warehousing systems. Application areas addressed by implementations of ISO/IEC 13249:2003 include, but are not restricted to, library, newspaper, multimedia and scientific research applications.
