The star schema and the snowflake schema are ways to organize data marts or entire data warehouses using relational databases. Both of them use dimension tables to describe data aggregated in a fact table. Everyone sells something, be it knowledge, a product, or a service.
The snow density data was then applied to temperature. Figure 3 shows a comparison of the air temperature and the snow density for the three highest sampling stations. Figure 3: Scatterplot showing the relationship between air temperature and snow density (stars). Also shown are breakpoints (triangles) obtained from the NWS meltwater conversion table.
