Data Manipulation Language (DML) is a subset of SQL (Structured Query Language) that allows users to interact with and manage data stored in a database. It includes commands like INSERT, UPDATE, and DELETE, which enable users to add new records, modify existing ones, or remove data as needed. DML is essential for maintaining the accuracy and relevance of data in applications. Using DML, developers can efficiently handle data operations without needing to understand the underlying complexities of the database management system. This makes it easier for businesses to analyze and utilize their data effectively, supporting informed decision-making and operational efficiency.
