Here's why:
* Schema Definition: DDL is specifically designed for creating, altering, and dropping database objects like tables, views, indexes, and constraints. This is what defines the schema of a database.
* Structure and Relationships: DDL commands allow you to define the structure of your tables (columns, data types, primary keys), establish relationships between them (foreign keys), and enforce data integrity rules (constraints).
Examples of DDL commands:
* CREATE TABLE: To define a new table.
* ALTER TABLE: To modify an existing table.
* DROP TABLE: To delete a table.
* CREATE INDEX: To create an index for faster data retrieval.
* CREATE VIEW: To create a virtual table based on an underlying table.
Important Note: While DDL is used to define the schema, Data Manipulation Language (DML) is used to interact with the data within that schema (insert, update, delete).
