Why NoSQL is Used Over SQL​

NoSQL databases are chosen over traditional SQL (relational) databases in scenarios where:

1. Flexible Schema​

• NoSQL allows dynamic, schema-less data structures (e.g., JSON, BSON).
• Useful when data models change frequently or are not well-defined upfront.

2. Scalability​

• NoSQL databases are designed for horizontal scaling (adding more servers).
• Ideal for handling large volumes of data and high-traffic applications.

3. Performance​

• Optimized for high-speed read/write operations.
• Can handle big data and real-time web apps more efficiently.

4. Handling Unstructured Data​

• Supports storage of unstructured, semi-structured, or nested data (e.g., documents, key-value pairs, graphs).
• Suitable for use cases like social media, IoT, and content management.

5. High Availability and Fault Tolerance​

• Many NoSQL databases offer built-in replication and distribution.
• Ensures data is always available, even if some nodes fail.

6. Big Data and Real-Time Analytics​

• NoSQL is often used for big data analytics, streaming, and real-time processing.

Setting Up a Local SQL Connection​

Step 1: Install a Database Server​

MySQL/MariaDB​

# Ubuntu/Debian
sudo apt install mysql-server

# macOS (using Homebrew)
brew install mysql

# Windows
