Archie is developing a library management system to manage books, authors, and borrowers. The system needs to handle three main types of data: BOOKS, AUTHORS, and BORROWERS.Write the DDL statements to create the following tables with the mentioned constraints to handle the data: symbol refers to the primary key NN refers to Not NULL After creating the tables, Archie needs to:Alter the BOOKS table to change the primary key to Title to ensure each book is uniquely identified by its title.Drop the primary key from the BORROWERS table as it is no longer requiredAlter the AUTHORS table to change the Nationality to NULL Note: The user must write only the query to create and alter the table. The query to display the description of the table is already given.Input format :No console inputOutput format :The output displays the successful table creation status and the structure of all three tablesRefer to the sample output.Sample test cases :Input 1 :Output 1 :Table BOOKS created.Table AUTHORS created.Table BORROWERS created.Table BOOKS altered.Table BOOKS altered.Table BORROWERS altered.Table AUTHORS altered.

Alexander is developing a ride-sharing application to track drivers, vehicles, and trips. The system needs to handle three main types of data: DRIVERS, VEHICLES, and TRIPS. Write the DDL statements to create the following tables with the mentioned constraints to handle the data: The DRIVERS table has a named primary key constraint pk_driver.The VEHICLES table has a named primary key constraint pk_vehicle for VehicleID and a named foreign key constraint fk_driver for DriverID.The TRIPS table has a named primary key constraint pk_trip for TripID and a named foreign key constraint fk_vehicle for VehicleID.symbol refers to the primary key NN refers to Not NULLAlexander ensures the following constraints are altered:Remove the foreign key constraint named fk_driver from the VEHICLES table.Note: The user must write only the query to create and alter the table. The query to display the description of the table is already given.Input format :No console inputOutput format :The output displays the successful table creation status, the structure of all three tables, and the existing foreign key constraint details.Refer to the sample output.Sample test cases :Input 1 :Output 1 :Table DRIVERS created.Table VEHICLES created.Table TRIPS created.Table VEHICLES altered.

Dia is responsible for managing a pharmaceutical production and distribution system. This system tracks information about drugs, production batches, and shipments. She needs to ensure that the data across these tables is accurate and meaningful.Write the DDL statements to create the following tables with the specified constraints:symbol refers to the primary key NN refers to Not NULL Create the DRUG table to store information about different drugs.Create the BATCH table with a foreign key constraint named FK_DRUG_ID to reference the DRUG table's DRUG_ID column, ensuring each batch is associated with a specific drug. Include a check constraint named CK_QUANTITY to ensure the QUANTITY column has a positive value.Create the SHIPMENT table with a foreign key constraint named FK_BATCH_ID to reference the BATCH table's BATCH_ID column, ensuring each shipment is linked to a specific production batch. Include a check constraint named CK_QUANTITY_SHIPPED to ensure the QUANTITY_SHIPPED column has a positive value.Note: The user must write only the query to create and alter the table. The query to display the description of the table is already given.Input format :No console inputOutput format :The output displays the successful table creation status and the structure of all three tablesRefer to the sample output.Sample test cases :Input 1 :Output 1 :Table DRUG created.Table BATCH created.Table SHIPMENT created.
