What is a common task performed using Data Manipulation Language (DML)?

• A. Updating existing records
• B. Defining views and indexes
• C. Creating database backups
• D. Establishing database connections

Answer: (A)

Data Manipulation Language (DML) consists of commands that are used to manipulate data within a database. One of the primary tasks performed with DML is updating existing records. This involves modifying the data already stored in a database, allowing users to change values, correct errors, or adjust information as needed. DML provides the functionality that ensures the data remains current and accurate according to the users' requirements. The other options relate to different categories of SQL commands or database operations. Defining views and indexes falls under Data Definition Language (DDL), which is focused on defining and managing database structures rather than manipulating the data within them. Creating database backups is an operation that typically requires administrative tools or scripts outside of direct data manipulation commands. Establishing database connections is part of the database interaction process but is not classified under data manipulation itself; instead, it pertains to connection protocols or setup configurations necessary for accessing the database system.
