IMCA - Introduction to RDBMS

1. **Used to Work with Tables**  
   SQL helps you create, manage, and get data from tables in a database.

2. **Easy to Learn and Use**  
   It uses simple English-like commands like `SELECT`, `INSERT`, `UPDATE`, `DELETE`.

3. **Works with Relationships**  
   SQL helps connect data from different tables using keys like **Primary Key** and **Foreign Key**.

4. **Supports Multiple Users**  
   Many people can use and work with the same database at the same time without losing data.

5. **Keeps Data Safe and Accurate**  
   It supports **ACID properties** — meaning data stays correct and safe even during errors or crashes.

6. **Allows Filtering and Sorting**  
   You can search for specific data, sort it, group it, and do calculations using SQL.

7. **Has Predefined Commands**  
   Comes with built-in commands for:
   - Creating databases/tables
   - Inserting/updating/deleting data
   - Controlling access and security

8. **Runs on All Major RDBMS**  
   Works the same way in systems like MySQL, Oracle, SQL Server, PostgreSQL, etc., though some features may vary.

9. **Supports Transactions**  
   You can group multiple operations together and make sure they all happen or none do (using `COMMIT` and `ROLLBACK`).

10. **Handles Large Amounts of Data**  
    SQL is powerful enough to manage big databases with millions of records efficiently.
