Question
Which of the following is used in the application programs to request data from the database management system?a.Data Definition Languageb.All of the abovec.Data Control Languaged.Data Manipulation language
Solution
The correct answer is d. Data Manipulation Language.
Data Manipulation Language (DML) is used in application programs to request data from the Database Management System (DBMS). It allows users to access and manipulate data in a database. This includes retrieving, inserting, updating, and deleting data from a database. Examples of DML commands include SELECT, INSERT, UPDATE, and DELETE.
Data Definition Language (DDL) and Data Control Language (DCL) are also part of SQL but they serve different purposes. DDL is used to define and manage tables and other types of database structures. DCL is used to control the visibility of data in a database and manage who has the permissions to perform certain actions.
So, while all of these are used in interacting with a DBMS, it's the Data Manipulation Language that is specifically used to request data.
