DDL usually means “Data Definition Language” in computing. It refers to the part of SQL used to create, change, or remove database structures like tables, indexes, and schemas.
In everyday tech use, people mention DDL when talking about database setup or changes. For example, a developer might use DDL to create a new table, add a column, or delete a table during database work.
Meaning & Usage
DDL is used when you want to define how data is organized in a database. Common DDL commands include CREATE, ALTER, and DROP. These commands change the structure of the database, not the data inside it.
Examples
You might hear: “We need to run DDL to create the new customer table.” Or: “This change requires DDL because the database structure is being updated.”
