Star Schemas. The star schema is perhaps the simplest data warehouse schema. It is called a star schema because the entity-relationship diagram of this schema resembles a star, with points radiating from a central table. The center of the star consists of a large fact table and the points of the star are the dimension tables.

Men om du skall ha y/d-start: Det allra enklaste är att ta 3 återfjädrande tryckknappar. 1 drar kontaktor 1 i y-läge utan hållkrets, denna hålls inne tills motorn slutat accelerera. Tryck därefter på knapp 2 som drar kontaktor 2 i d-läge med hållkrets. Motorn går nu i d-läge tills knapp 3 trycks in. Vid Y/D-start sker själva strömintroduktionen och uppvarvningen via Y-koppling (låg spänning) för att sedan ställas om till D-koppling (hög spänning) först när varvtalet börjar avta. Därigenom får man en betydligt lägre startströmsbelastning, vilket också minskar risken för kraftiga strömtoppar och korresponderande spänningsdippar i elnätet.
Now that you know about the dimension and fact tables, it is time to talk about one of the most important concepts of modeling. You might have heard about dimensional modeling or star schema, but you may have vague ideas about what it is, or alternatively, you might have used it, but not sure if Read more about Power BI Basics of Modeling: Star Schema and How to Build it[…]

Snowflaking normalizes the dimension by moving attributes with low cardinality into separate dimension tables that relate to the core dimension table by using foreign keys. Unlike Star schema, the dimensions table in a snowflake schema are normalized. For example, the item dimension table in star schema is normalized and split into two dimension tables, namely item and supplier table.
