1. **SQL (Structured Query Language)** is used to manage and manipulate relational databases. 2. **DDL (Data Definition Language)** includes commands like `CREATE`, `ALTER`, and `DROP` to define or modify database structures. 3. **DML (Data Manipulation Language)** involves `SELECT`, `INSERT`, `UPDATE`, and `DELETE` for working with data. 4. **DCL (Data Control Language)** includes `GRANT` and `REVOKE` to manage access permissions. 5. **TCL (Transaction Control Language)** commands like `COMMIT`, `ROLLBACK`, and `SAVEPOINT` manage transactions. 6. SQL documents typically contain scripts that define tables, constraints, indexes, and data. 7. These documents help automate database setup, maintenance, and data handling. 8.
