A random generation rule is a global or ad hoc rule that creates random string, numeric, and date values. You can use random generation to generate data such as salary and birth dates.
When you configure random generation, you can specify a minimum and maximum length for data strings and a minimum and maximum value for numeric data. You can include a regular expression to create a fixed percentage of the generated data. The percentages of the pattern distributions must total 100. When you generate dates, you can select a start date and end date to create random dates within a range.
Random generation rules can be global rules or ad hoc rules.

Random Generation Example
You want to generate addresses for customers. You create a rule that uses the random technique and the string data type. You define a regular expression in the rule. The regular expression creates rows with a four digit number, a random string of 12 characters, and "St." or "Ave." You set the pattern percentage to 100 to generate all the rows with the regular expression.
