# Denormalized antecedents dataset 
 
Remember that a rule materializes the relationship between an antecedent itemset and a consequent itemset. 
An itemset being a set of items, denormalizing the rule antecedents allows getting a data format giving all the antecedent items of a given rule.
 
Dataset [rules_denormalized_antecedents](dataset:rules_denormalized_antecedents) contains the information of the rules present in [association_rules](dataset:association_rules), denormalized based on their antecedent.
 
**Dataset Granularity**:  
- IF you *DON'T CHOOSE TO* compute granular association rules: 1 row = 1 antecedent item of a rule.
- ELSE : In addition, each row gives you information on the granularity each antecedent and rule belongs to.
