Native Transactional Data and Star Schemas
Store transactional data in native or star schema formats, transforming non-native formats for Apriori processing.
Transactional data may be stored in native transactional format, with a non-unique case ID column and a values column, or it may be stored in some other configuration, such as a star schema. If the data is not stored in native transactional format, it must be transformed to a nested column for processing by the Apriori algorithm.
