Which SQL programming technique should a university utilize for adding a new course and updating student records?

• A. DML for both actions
• B. DDL to create new records
• C. TCL for transaction management
• D. Set-based logic for updates

Answer: (A)

The correct answer highlights the use of Data Manipulation Language (DML) for both adding a new course and updating student records, which is appropriate because DML is specifically designed for managing and manipulating the data within a database. DML includes operations such as INSERT, UPDATE, DELETE, and SELECT. When a university needs to add a new course, the INSERT statement from DML is utilized to add the new course information into the courses table in the database. Likewise, when updating student records, the UPDATE statement is employed to modify existing entries in the student records table. Since both operations—adding a course and updating records—are focused on altering the data, using DML for both is the most suitable approach. In contrast, Data Definition Language (DDL) is intended for defining and modifying database structures, such as creating or altering tables, but not for manipulating the data contained in them. Transaction Control Language (TCL) is more about managing transactions, ensuring data integrity through commit and rollback operations, rather than performing the actual data manipulations. Set-based logic refers to performing operations on sets of data rather than individual rows, which can be a feature of DML but does not encapsulate the entire requirement as succinctly as DML itself. Thus
