Is relationship between tables are only based on ID?
Relationships between tables in a database are not always based solely on the ID field. In addition to primary and foreign key relationships, relationships can also be established between a dimension and a metric. A dimension is a descriptive attribute of data, while a metric is a measurable attribute. By establishing relationships based on shared attributes, such as a common time period or location, we can better analyze and understand the data in our database.
