Classic database normalization would say to create a pizza table, and then a many-to-many table relating pizza IDs to topping IDs.
典型的数据库标准会建议需要先创建一张比萨表,然后再创建一张将比萨id与浇头id关联起来的多对多表。
Note that this is an extremely informal discussion of the topic of database normalization, and does not cover all of the issues in depth.
注意这是对数据库规范化的一个非常不正式的讨论,并且也没有深入讨论所有的主题。
Database normalization is a data design and organization process applied to data structures based on rules that help building relational databases.
数据库规范化是一种基于规则的,施加于数据结构之上的数据设计和组织过程,这种规则有助于建立关系型数据库。
To demonstrate, let's apply a little database normalization to the previous example, splitting the owner field of PhoneNumber into a separate person table.
作为演示,我们将一个小的数据库规范化(normalization)应用于上一示例,将PhoneNumber的owner字段分割到单独的person表中。
Normalization is also left by the wayside (as it usually is in any large database in which performance is a major concern).
标准化也被抛到了脑后(因为通常在大型的数据库中,性能是主要关注点)。
Note that normalization is standard practice in any database-oriented application.
注意数据的规范化在任何面向数据库的应用程序中都是标准实践。
Normalization usually involves dividing a database into two or more tables and defining relationships between the tables.
规范化通常包括:将一个数据库拆分为两个或更多的表,并定义表之间的依赖关系。
In relational database design, the process of organizing data to minimize redundancy is called normalization.
在关系型数据库设计中,这种组织数据以减少冗余的过程,被称为规范化。
In this paper, the application of normalization and denormalization in the optimization of relational database design are discussed.
讨论了在大型关系数据库优化设计中关系的规范化和逆规范化的应用。
With connection to the proposed database table, the processing methods and techniques for normalization, ranking and inquiry on fuzzy information are also discussed.
结合所提出的数据库表,探讨了模糊数据的归一化、排序、查询等处理方法与技术。
Remember, these normalization guidelines are cumulative. For a database to be in 3NF, it must first fulfill all the criteria of a 2NF and 1NF database.
记住,这些规范化准则是渐增的。如果一个数据库满足第三范式,那么它必须先满足了第二范式和第一范式的条件。
