Which term refers to the language that defines database structure (such as creating or altering tables)?

• A. DDL
• B. Cursor
• C. Cookie
• D. CSS

Answer: (A)

Defining and changing how data is organized in a database is handled by Data Definition Language. This part of SQL includes commands like CREATE to build new tables, ALTER to modify existing ones, and DROP to remove structures. These statements focus on the schema—the layout of tables, columns, data types, and relationships—not on querying or manipulating the actual data.

A cursor, on the other hand, is a mechanism for iterating over rows in a result set, typically used in procedural code to process data one row at a time. It doesn’t define or modify the database structure.

Cookies are small pieces of data stored by web browsers to track sessions or preferences, not related to database schema. CSS controls the presentation and styling of web pages, not database definitions.

Because the question asks for the language that defines database structure, the correct term is Data Definition Language.
