In the context of [[SQL]], '''data definition''' or '''data description language''' ('''DDL''') is a syntax for creating and modifying database objects such as tables, indices, and users. DDL statements are similar to a computer [[programming language]] for defining [[data structure]]s, especially [[database schema]]s. Common examples of DDL statements include <code>CREATE</code>, <code>ALTER</code>, and <code>DROP</code>. If you see a .ddl file, that means the file contains a statement to create a table. Oracle SQL Developer contains the ability to export from an ERD generated with Data Modeler to either a .sql file or a .ddl file.
