In terms of database operations, what does DML primarily modify?

• A. Database schemas
• B. Database permissions
• C. Data instances
• D. Database functions

Answer: (C)

DML, or Data Manipulation Language, is fundamentally concerned with the management of data stored within a database. It includes operations that allow users to insert, update, delete, and retrieve data from a database. When we refer to modifying data, we are specifically discussing the changes that happen to the actual data instances—this involves the records in the tables of a database. For instance, if a person updates their address in a user database, that specific action alters the data instance for that record. Similarly, if new records are added or existing records are removed, these are also operations governed by DML. The focus is squarely on the data itself rather than on structural aspects like database schemas, permissions, or functions. Thus, DML is directly responsible for alterations to the actual data, making data instances the correct answer.
