For inserting a new record of a rented vehicle and creating a new table simultaneously, which SQL techniques should a car rental company employ?

• A. DDL for both tasks
• B. DML for inserting the record and DDL for creating the table
• C. DML for both tasks
• D. DDL for inserting the record and DML for creating the table

Answer: (B)

To effectively handle the tasks of inserting a new record for a rented vehicle while simultaneously creating a new table, the correct approach involves using Data Manipulation Language (DML) and Data Definition Language (DDL) appropriately.

When creating a new table, DDL is essential. This subset of SQL is specifically designed for defining and managing all structural aspects of the database, including table creation, alteration, and deletion. In this case, the organization needs to define the new table structure that will store the relevant information about the rented vehicle.

On the other hand, to insert the actual data record into a table, DML is used. DML includes commands such as INSERT, UPDATE, and DELETE, which allow for the manipulation of data within the tables. Therefore, once the new table has been created using DDL, the subsequent step involves using DML to insert the specific details of the rental vehicle into this new structure.

This division of responsibilities ensures that the creation of the table and the insertion of data are handled with the proper SQL techniques, allowing for efficient database management and ensuring integrity in both structural and operational aspects of the database.
