Question

Quizplus · Accepted Answer

A data definition language (DDL) is used to define the data and relationships within a database. It is used to create, alter, and delete tables, indexes, and constraints within a database. QBE (Query By Example) is a graphical user interface for performing database queries, it is not a DDL. Size is not defined by a DDL, but can be affected by the definition of the data and relationships within the database. The model can refer to the overall design or structure of the database, but the DDL specifically focuses on defining the data and relationships.
