Question
DDL is the abbreviation of
A. Data Definition Language
B. Data Derivation Language
C. Description Language
Solution
The correct answer is A: Data Definition Language.
Explanation:
DDL, or Data Definition Language, is a subset of SQL (Structured Query Language) used to define, modify, and remove database schemas, tables, indexes, and other structures. It includes commands such as CREATE, ALTER, and DROP, which are essential for database management and structure definition.
While "Data Derivation Language" and "Description Language" are terms you might come across in other contexts, they do not relate to the common understanding of DDL in database terminology. Thus, when referring to DDL, it is universally recognized as Data Definition Language.
