What is the difference between DDL and DML in DBMS?
In Database Management Systems (DBMS), Data Definition Language (DDL) and Data Manipulation Language (DML) are two distinct categories of SQL commands, each serving different purposes. Understanding the differences between them is crucial for anyone working with databases, especially when it comes to creating, managing, and manipulating data. DDL and DML are both essential components in the interaction between users and databases, but they differ in their functionality, scope, and the types of tasks they handle.
Data Definition Language (DDL):
DDL refers to the set of SQL commands that are used to define and manage the structure of a database. It is primarily concerned with the creation, alteration, and deletion of database objects such as tables, schemas, and indexes. DDL commands describe how the data should be stored, organized, and related within the database. These commands do not manipulate the data itself but deal with its schema and structure.
Key DDL Commands include:
-
CREATE: This command is used to create new database objects such as tables, views, schemas, indexes, or even entire databases. For example, a
