You can define validation rules in data modeling tools and reuse the rules. Metadata Manager stores one instance of the validation rule for each column or domain that uses the rule.
In data modeling tools, there is a one-to-many relationship between validation rules and columns or domains. To identify each validation rule for each column or domain, Metadata Manager renames each validation rule based on the column or domain name.
The following table shows a validation rule VR1 that is used by columns X and Y and the domain DOM:

Metadata Manager renames validation rule, VR1, to the column and domain names, X, Y, and DOM.
Metadata Manager extracts validation rules that are used in columns or domains.
