What is data manipulation language commonly used for?

1. Choosing colors and layouts in apps

2. Graphics design in software applications

3. Querying and manipulating database data

4. Editing video files

The correct answer is: Querying and manipulating database data

Data Manipulation Language (DML) is specifically designed for interacting with databases, enabling users to perform operations such as querying, updating, inserting, and deleting data within a database management system. This functionality is essential for managing the stored data effectively to retrieve meaningful information and alter database entries as required by applications or organizational needs. By utilizing DML, users are able to write queries that seek specific data (querying) and also modify existing data or add new records (manipulating). This makes DML a crucial component of database management, as it directly supports the operations necessary for maintaining and utilizing data effectively, contributing to informed decision-making and analysis within supply chain management and many other fields. The other options do not relate to DML and instead pertain to unrelated fields such as app design, graphic design, or video editing, which focus on visuals and multimedia rather than the structured operations on data within databases.
