Snowflake (heraldry) The snowflake or "snow crystal", is a charge in heraldry. The display in coats of arms is following a strictly stylized form of the natural six pointed crystal form of a snowflake. In older heraldic literature, this charge is not to be seen. In modern heraldry, the snowflake is most used in northern Europe, in arms in Sweden, Norway and Finland, where it alludes to the meteorological features of the lands. Otherwise, it also is a symbol for winter, and
Snowflake schema is similar to the star schema. However, in the snowflake schema, dimensions are normalized into multiple related tables, whereas the star schema's dimensions are denormalized with each dimension represented by a single table. A complex snowflake shape emerges when the dimensions of a snowflake schema are elaborate, having multiple levels of relationships, and the child tables have multiple parent tables ("forks in the road"). Star and snowflake schemas are most commonly found in dimensional data warehouses and data marts where speed of data retrieval is more important than the efficiency of data manipulations. As such, the tables in these schemas
