The CTAS statement is used to create a new table by copying all data from an existing table without any transformation, ensuring data integrity but not addressing storage or performance optimization.

The CTAS statement is used to create a new table by merging data from multiple tables, which increases storage costs and does not necessarily optimize query performance for the reporting feature.

The CTAS statement is used to create a new table by partitioning the data from an existing table, which improves query performance but does not allow for data transformation or filtering.

The CTAS statement is used to create a new table based on the result of a SELECT query, allowing for data transformation and filtering, which can help in minimizing storage costs and optimizing query performance for the reporting feature.
