Each binary logging format has advantages and disadvantages. == Trouble. The advantages of a snowflake model: Reduced redundant data, which implies reduced storage size More scalable for writes More flexible The disadvantages: More complexity by a higher number of tables Harder to understand by business users Reduced query performance Since unstructured data does not have a predefined data model, it is best managed in non-relational (NoSQL) databases.
