Dimension Table VS Fact Table in Kimball DWH

Dimension tables contain descriptive information about a subject or matter. 

Dimension tables contain hierarchies of attributes that aid in summarization. 

For example, 

A "Student" dimension table contains descriptive information about Student -> (Name, Age, Gender, Address, Phone_No etc.)

A class dimension table contains descriptive information about class -> (Class_Name)

and a Subject dimension table contains detail information about subject -> (Subject_Name).

Note: Dimension tables contain attributes that describe fact records in the fact table.

Fact table contain summarized data to provide useful information to the analyst. 

The fact data is a relation/ Referential integration between various Dimention(Subject) Table data.

Here we can see it is a collection of only ids of other dimension Tables and forms useful information to the analyst.
