The repository design for the purpose of an online data warehouse may be either dimensional or hierarchical. A dimensional style organizes info into tables that are methodized following database normalization rules. Every table has one or more main keys that define what produces a unique row in the databases. This approach makes the data better to understand also to retrieve, since it is arranged into measurements/facts and context/dimensions.
