Each standard data generator that is numeric (Decimal, Money, DateTime, Real, Float, and the integer generators) has a Distribution property. The user can specify the Distribution property to generate data that approximates a statistical distribution curve. The standard distribution options are as follows: Uniform, Normal, Normal Inverse, Exponential, and Exponential Inverse.

One instance of the designer exists for each distribution that is associated with each numeric column that the data generation plan includes.
