The next component is data modeling. You need to learn the following core concepts.

Data table: the table containing the facts such as daily sales or purchases.

Lookup table: the table that describes the facts and gives us details for deeper analysis

Primary key: This is the unique ID column in the lookup table

Foreign key: This is found in Data table and contains multiple rows of the primary key column.
