Abstract

Abstract: Acyclic database has many good characteristics, so acyclic is an important characteristic for database schema. Based on γ acyclic database schema, this paper presents the definitions of none XML_ cycle, the characteristics of none XML_ cycle in XML documents and design method of XML schema for none XML_ cycle. Theory analysis proves the effectiveness of the rules designed.

Key words: normalization, ambiguity, XML_ cycle

摘要： 无环数据库有许多优良特性，因此，无环成为判断数据库模式优劣的重要特性。针对以上情况，以关系数据库中无环数据库模式为参考，给出XML文档中无XML_ 环的相关定义、表示、特征及无XML_ 环的XML数据模式的设计方法，理论分析证明，所设计的规则是有效的。

关键词: 规范化, 二义性, XML_ 环
