1. Although the term denormalization is used in this section, the process does not apply just to relational data models. — — 虽然非普适方法被使用在这章,这个过程不仅仅使用在关系数据模型。 For example, one can denormalize in a document database, but it would be called something different – such as embedding. — — 举例,在文档数据库使用非普适方法,它能够被调用通过不同的方案,如使用embedding
2. In dimensional data modeling, denormalization is called collapsing or combining(在维度建模中,非普适方法被折叠和组合调用). If each dimension is collapsed into a single structure(如果每一个维度被折叠到单一结构), the resulting data model is called a Star Schema(其被称为星型模型). If the dimensions are not collapsed, the resulting data model is called a Snowflake(如果维度没有被折叠,这个最终数据模型被称为雪花模型).

我不行啦!妹妹你选的这是什么歌?这个歌词怎么回事!?
Won’t you give yourself to me? Give it all.
Where you go I follow, no matter how far.
If life is a movie, you are the best part.
When we wake up and then we make love.
If you love me won’t you say something?

#指南西班牙语新闻# El Consejo de Ministros de este martes decidía que las medidas impulsadas por el Gobierno a raíz de la pandemia por el coronavirus se prolongan hasta septiembre. Sin embargo, esta circunstancia ha sido desplazada del foco por el ataque de Podemos a la prensa y también por las noticias sobre los negocios de Juan Carlos I. Pablo Iglesias se sometía por primera vez a una comparecencia desde que estallara el caso Dina. El vicepresidente segundo del Gobierno ha mantenido el ataque hacia medios críticos con su formación e, incluso, ha considerado "natural" que los periodistas reciban "insultos" o "cosas desagradables" desde las redes sociales.
