Data Retrieval: Querying and extracting data from databases.
Data Manipulation: Inserting, updating, and deleting records.
Data Definition: Creating and modifying database structures.
Data Control: Managing user permissions and access rights.
Transaction Management: Ensuring data consistency and integrity.
Query Optimization: Improving query performance.

SQL is fundamental to working with relational databases in various applications.

2. What are the basic SQL commands for data retrieval?

Basic SQL commands for data retrieval include:

SELECT: Retrieves data from one or more tables.
FROM: Specifies the source table(s) for the data.
WHERE: Filters rows based on specified conditions.
GROUP BY: Groups rows based on specified columns.
HAVING: Filters grouped rows based on conditions.
ORDER BY: Sorts result rows based on specified columns.

These commands are essential for querying and extracting specific data from databases.

3. How do you perform data manipulation in SQL?

Data manipulation in SQL involves commands like:

INSERT INTO: Adds new records to a table.
UPDATE: Modifies existing records in a table.
DELETE FROM: Removes records from a table.

These commands enable changing data within a database while maintaining data integrity and consistency.

4. What is the importance of database normalization in SQL?

Database normalization is crucial for:

Data Integrity: Reducing data redundancy and inconsistency.
Efficient Storage: Minimizing storage space and optimizing performance.
Query Optimization: Simplifying queries and improving efficiency.
Maintenance: Making updates, inserts, and deletes easier.
Flexibility: Adapting to changing requirements without major modifications.

Normalization ensures databases are organized and optimized for effective data management.

5. What are SQL joins and how do they work?

SQL joins combine data from multiple tables based on related columns. Types of joins include:

INNER JOIN: Returns rows with matching values in both tables.
LEFT JOIN (OUTER JOIN): Returns all rows from the left table and matching rows from the right table.
RIGHT JOIN (OUTER JOIN): Returns all rows from the right table and matching rows from the left table.
FULL OUTER JOIN: Returns all rows when there are matches in either table.
