💡 What is Big Data?

Big Data refers to extremely large datasets that are too complex to be handled by traditional data-processing systems.

It's not just about size — it’s about:

• Volume 🧱: Tons of data generated every second
• Velocity ⚡: Data is generated in real-time
• Variety 🍕: Data comes in all forms — text, images, videos, logs, sensors
• Veracity ❓: Ensuring data accuracy and trustworthiness
• Value 💰: Extracting useful insights that matter

This is often called the 5 V's of Big Data.
