The database language concerned with the definition of the whole database structure and schema is DDL (Data Definition Language).
DDL (Data Definition Language) is a subset of SQL (Structured Query Language) that is used to define and manage the structure of a database. It allows users to create, modify, and delete database objects such as tables, views, indexes, and constraints.
Some key points about DDL include:
- It is used to define the structure of the database, including the tables, columns, data types, relationships, and constraints.
- DDL statements do not manipulate or retrieve data, but rather define the structure and organization of the database.
- DDL statements include CREATE, ALTER, and DROP statements.
- CREATE statement is used to create new database objects like tables, views, and indexes.
- ALTER statement is used to modify the structure of existing database objects.
- DROP statement is used to delete or remove database objects.
Examples of DDL statements:
- CREATE TABLE: Used to create a new table in the database.
- ALTER TABLE: Used to modify the structure of an existing table.
- DROP TABLE: Used to delete a table from the database.
In summary, DDL is the database language that is concerned with defining and managing the structure of the database, including creating, modifying, and deleting database objects.
