Abstract: Techniques for database normalization recommendation and transparent database normalization are described. A normalization engine can analyze the data stored by database tables to determine scenarios in which normalization of the tables may be beneficial. The normalization engine can recommend normalization to an end user, such as during a database migration process. The normalization engine can alternatively perform row-by-row or complete columnar normalization and cause queries issued against normalized tables based on the previous table schema to be automatically rewritten to adhere to the updated data layout.
