Columnar Storage Is Normalization

Columnar storage physically realizes the mathematical principles of database normalization—row reconstruction from columns mirrors join operations in normalized schemas, making them equivalent design patterns.

The article explains columnar storage as a form of database normalization within relational abstraction. Using concrete examples, it contrasts row-oriented layouts (efficient for row access/inserts) with column-oriented layouts (efficient for column-specific queries). The key insight: reconstructing rows from columnar storage is logically equivalent to a join operation on normalized tables.
