Answer:
True. The database schema is defined by the Data Definition Language (DDL) components in the SQL programming language.
Step-by-step explanation:
A database schema is a blueprint that outlines the structure, organization, and relationships among the tables and other database objects in a database management system (DBMS). In SQL, the Data Definition Language (DDL) is a subset of SQL commands that are used to define and manage the structure of a database, including creating, altering, and deleting tables, constraints, and other database objects.
DDL includes commands such as CREATE, ALTER, and DROP, which allow you to create, modify, and delete database objects like tables, indexes, and views. These commands are responsible for defining the structure of the database and its components, which together form the database schema.
For example, the CREATE TABLE command is a DDL statement that allows you to define a new table's structure, including the table name, column names, data types, and constraints. This definition becomes part of the database schema, which represents the overall structure and organization of the database.
In summary, the database schema is indeed defined by the DDL components in the SQL programming language, as DDL commands are used to create, modify, and manage the structure and organization of database objects.
