✅ DQL (Data Query Language): Retrieve data from databases using commands like:

• SELECT — Extract specific data from tables.
• WHERE — Filter records based on conditions.
• JOIN — Combine rows from multiple tables.

✅ DML (Data Manipulation Language): Modify data with commands such as:

• INSERT — Add new records.
• UPDATE — Modify existing records.
• DELETE — Remove records.

✅ DDL (Data Definition Language): Define and manage database structures:

• CREATE — Add new tables or databases.
• ALTER — Modify table structures.
• DROP — Remove tables or databases.

✅ DCL (Data Control Language): Control access to the database with:

• GRANT — Provide specific privileges to users.
• REVOKE — Remove previously granted privileges.

✅ TCL (Transaction Control Language): Manage transactions to maintain data integrity:

• COMMIT — Save changes permanently.
• ROLLBACK — Undo changes if an error occurs.

Mastering these commands gives you the power to handle data efficiently, ensuring your applications run smoothly and securely. 🚀
