Hi There;
I am reading here in order to implement data warehouse : https://docs.oracle.com/database/121....htm#DWHSG8169
The topic is about Materialized View Schema Design.

Here there is a paragraph:

In the case of normalized or partially normalized dimension tables (a dimension that is stored in more than one table), identify how these tables are joined. [önemli] Note whether the joins between the dimension tables can guarantee that each child-side row joins with one and only one parent-side row. In the case of denormalized dimensions, determine whether the child-side columns uniquely determine the parent-side (or attribute) columns.
What is the child side row and parent side row in this context?

Thanks in advance.
