“DML” stands for “Data Manipulation Language.” It is a subset of SQL (Structured Query Language), which is a standardized language for managing and manipulating relational databases. DML specifically focuses on the operations involved in retrieving, inserting, updating, and deleting data within a database management system (DBMS). DML commands are essential for working with the data stored in a database, and they enable users to interact with and modify the content of database tables.
Key DML commands in SQL include:
SELECT: The SELECT statement is used to retrieve data from one or more tables in a database. It allows users to specify which columns and rows of data they want to retrieve, making it a powerful tool for querying and reporting.
INSERT: The INSERT statement adds new rows of data into a table, allowing users to input data into the database.
UPDATE: The UPDATE statement modifies existing data in a table. It allows users to change the values of specific columns for one or more rows.
DELETE: The DELETE statement removes rows from a table, effectively deleting data from the database.
DML commands are crucial for managing and maintaining the integrity of a database, ensuring that it accurately reflects the current state of an organization’s data. These commands enable users to perform tasks like retrieving customer information, adding new products, updating inventory records, and more. Understanding and effectively using DML commands is fundamental for anyone working with relational databases and is a fundamental aspect of database management.
As for other interpretations of “DML” in different contexts, none are as widely recognized as “Data Manipulation Language” in the field of database management.
