Hace un rato una costurera ha comentado en TVE que ha perdido su taller de costura en Paiporta (Valencia) tras la DANA, al rato una costurera de Murcia que se acaba de jubilar ha llamado para donarle su taller.

Data warehouse schema designs

In most transactional databases that are used, the data is normalized to reduce duplication.

In a data warehouse, however, the dimension data is generally de-normalized to reduce the number of joins required to query the data.

Often, a data warehouse is organized as a star schema.

The fact table is directly related to the dimension tables, as shown in this example:

The attributes of an entity can be used to aggregate measures in fact tables over multiple hierarchical levels.

For example, to find total sales revenue by country or region, city, postal code, or individual customer.

The attributes for each level can be stored in the same dimension table.

When an entity has a large number of hierarchical attribute levels, or when some attributes can be shared by multiple dimensions.

For example, both customers and stores have a geographical address.

It can make sense to apply some normalization to the dimension tables and create a snowflake schema, as shown in the following example:

In this case, the DimProduct table has been normalized to create separate dimension tables for product categories and suppliers.

A DimGeography table has been added to represent geographical attributes for both customers and stores.

Each row in the DimProduct table contains key values for the corresponding rows in the DimCategory and DimSupplier tables.

Each row in the DimCustomer and DimStore tables contains a key value for the corresponding row in the DimGeography table.

"Go out and read some ML papers."

That's the most harmful advice for beginners.

They will understand nothing and fall into depression.

Those papers are the tip of the iceberg.

What they need is deep in the sea.
