When you create a standard generation rule, you select the generation technique. You can define one generation technique in a standard rule and you can apply the rule to one column at a time. You can apply the rule multiple times to different columns.
You can use standard generation techniques to generate string, numeric, date, and binary datatypes. The techniques vary based on the datatype.
For example, you create a standard generation rule with the random date technique to generate birth dates. You can assign the rule multiple times in a project to generate birth dates in more than one column or you can use the rule in multiple projects.
