Abstract
A method for generating schemas to compress storage of denormalized data includes receiving user selection of an initial data table and constructing a snowflake schema to decompose the initial data table into a plurality of tables. Tables in the plurality of tables that are related to one another are connected by foreign keys. The snowflake schema is constructed according to a cost model that balances the cost of storing the plurality of tables and the cost of storing the foreign keys. The method also includes transforming data in the initial data table into the plurality of tables according to the snowflake schema.
