Final answer:
The statement is false as a database definition language (DDL) is used for defining and modifying database structures, not for performing complex queries. For queries to transform data into useful information, the database manipulation language (DML) is the appropriate tool within SQL.
Step-by-step explanation:
The statement that a database definition language (DDL) enables the user to perform complex queries designed to transform the raw data into useful information is false. DDL is a computer language used in database management systems that defines the different structures in a database. It provides commands for creating, altering, and dropping tables and other objects in a database.
Complex queries are typically handled by a database manipulation language (DML), which is a part of SQL (Structured Query Language). DML allows users to perform operations such as insert, update, delete, and select to manage data within the database tables. These operations enable the transformation of raw data into useful information.
In summary, DDL is concerned with the structure and schema of a database, whereas DML deals with the manipulation of the data itself. They are complementary parts of SQL, but they serve different functions within the management and querying of databases.
