Modifying rule sets

How to identify gaps in current standardization practices
When input data changes, existing rule sets might become less effective. To meet new or changed standardization requirements, you change the way that rule sets process data by enhancing rule sets in the Standardization Rules Designer, using override object types, or modifying the pattern-action language.

How to choose a method for rule set management
You can modify a rule set by enhancing the rule set in the Standardization Rules Designer, using override object types, or modifying the pattern-action language. The method that you choose depends on your requirements and your experience with the pattern-action language.

Strategies for classification
You classify values in the input data to strengthen the contextual information that the values provide and group them into categories.

Customizing rule sets by using overrides
You can change the way that input data is processed by using overrides.

Enhancing standardization rule sets by using the Standardization Rules Designer
Use the IBM InfoSphere QualityStage Standardization Rules Designer to enhance standardization rule sets. After you enhance rule sets in the Standardization Rules Designer, you can apply the enhanced rule sets in a Standardize stage.

User modification subroutines
Occasionally, you need to make rule set modifications that are more complex than what can be done with user overrides. You must make the modifications by using the pattern-action language. Each rule set used for standardization has subroutines that are reserved for these modifications.
