摘要
简介了关系模型、键、完整性规则、E-R模型、函数依赖、模式分解和关系模式的范式等数据库技术基础和规范化设计理论,从键和完整性规则的实现、数据冗余的特殊情况和字典设计等方面论述了在实际设计工作中如何灵活运用关系数据库设计理论。
The technical basis and 'standard design theories for database, such as relation model, key, integrity regulation, E-R model, function dependence, mode resolution, normal form of relation schema, are firstly analyzed in this paper. And then, the flexible applications of design theories for relational database, in aspects of implementation of key and integrity regulation, special conditions of data redundancy, dictionary design, are introduced.
