我需要一个思维过程来设计OLAP数据库…
从本质上来说,标准关系是(宽松地): Identify Entities Identify Relationships Identify Properties of Entities 对于每个属性: Ensure property can be related to only one entity Ensure property is directly related to entity 对于OLAP数据库,我了解术语,动机和结构。但是,我不知道如何将我的关系模型分解为OLAP模型。
Identify Entities Identify Relationships Identify Properties of Entities
Ensure property can be related to only one entity Ensure property is directly related to entity
