It is a number.It tells you how the data is distributed
among Processors or Amps.Skew factor varies about 0-100.
If the data is distributed evenly among the processor the
skew factor is ZERO whether it is smaller or large table.
Skew factor doesn't depends on size of table but it only
depends on distribution of data.
If the skewfactor is more we have to access the table on
only primary index columns but not whole table.
