[2] Additionally, the time a snowflake was created can be calculated from the snowflake. This can be used to get snowflakes (and their associated objects) that were created before or after a particular ...
The horizontal partitioning will first partition the table into multiple row groups based on the row-group size, which is a user-specified value determining the size of each row group.

For example, a table of 128 rows with a Boolean column requires 128 bytes a row-oriented format (one byte per Boolean) but 128 bits (16 bytes) in a column-oriented format (via a bitmap). Another example is the use of run-length encoding to encode a column.
Examples of fact data include sales price, sale quantity, and time, distance, speed and weight measurements.

A star schema that has many dimensions is sometimes called a centipede schema. [4]
