DDL is used to create, modify, and delete database objects such as tables, indexes, and views. DDL statements define the schema of a database by specifying the data types, constraints, and relationships between the objects in the database.

IDML allows users to interact with the database in real-time and perform operations such as inserting, updating, and deleting data.   IDML provides a user-friendly interface for interacting with the database, making it easy for non-technical users to manipulate data without needing to know the underlying SQL commands. IDML also provides features like auto-complete and syntax highlighting to help users write correct and efficient queries.   Some examples of IDML include SQL Server Management Studio, Oracle SQL Developer, and MySQL Workbench. These tools provide a graphical interface for users to interact with the database and perform operations on data.   In summary, IDML is a user-friendly language used to manipulate data in a database through a graphical interface, making it easier for non...
