目前流行的各种大型数据库系统都缺乏对民族语言如藏、蒙、维文的支持。如何实现民文信息在数据库中存储、查询和检索等处理及支持各种基于民文的数据库应用,是一个重要问题。本文提出了一个数据库管理系统多民族语言支持框架,支持多民族语言、数据库客户端工具和应用编程接口;并在此框架下提出了一种符合ISO/IEC14651语义的藏文排序方法,从而实现了PostgreSQL数据库对藏文信息处理的全面支持。并在Linux平台的PostgreSQL数据库系统上加以实现。

Almost all the large database systems currently in use such as Oracle , Sybase and DB2 lack the support to minority languages of China. How to storage , query and index minority language information in databases and how to support database applications in such a multi-lingual environment are important tasks. This paper proposes a DBMS multi-lingual support framework for minority languages , along with a multinational language application programming interface. Moreover , it proposes a sorting algorithm for Tibetan words according to the semantics of ISO/IEC 14651 , leading to a full support in . PostgreSQL for Tibetan information processing . The framework has been implemented in PostgreSQL database on the Redflag Linux OS.
