2. Volume - The Size Monster 📊
Definition: The sheer amount of data being generated.
Scale Breakdown:
- Megabyte (MB): A few photos
- Gigabyte (GB): A movie
- Terabyte (TB): 1,000 movies
- Petabyte (PB): 1,000,000 movies
- Exabyte (EB): Google processes 20+ PB per day!
Indian Example:
- IRCTC: Handles 1 million+ ticket bookings daily during festival season
- Aadhaar: Stores biometric data of 1.3 billion Indians (massive!)
3. Velocity - The Speed Demon 🚀
Definition: The rate at which data is generated and needs to be processed.
Speed Categories:
| Type | Speed | Example |
|---|---|---|
| Batch | Hourly/Daily | Bank statements |
| Real-time | Seconds | Stock market prices |
| Streaming | Milliseconds | Live cricket score updates |
Why It Matters: During IPL matches, Hotstar processes 25 million concurrent users watching the same moment – that's velocity!
4. Variety - The Data Buffet 🍱
Definition: Different formats and types of data.

Semi-Structured: XML files, JSON (used in APIs)
5. Veracity - The Trust Factor ✅
Definition: Accuracy and reliability of data.
The Problem:
- Typos in customer names
- Duplicate entries
- Sensor errors (wrong temperature reading)
- Fake social media accounts
Example: If Zomato's data says "Customer rated 5 stars" but it was a bot, that's low veracity!
Bad data costs businesses $3 trillion annually worldwide. In India, incorrect customer data leads to failed deliveries and lost sales!
6. Value - The Money Maker 💰
Definition: Extracting meaningful insights that drive business decisions.
The Golden Question: "So what?"
Having petabytes of data is useless if you can't derive business value from it!
Value Chain:
Raw Data → Processing → Analysis → Insights → Better Decisions → ₹ Profit
Indian Success Story - Amazon India:
- Data: Customer browsing patterns
- Insight: People browse on phone but buy on laptop
- Action: Optimized mobile app for discovery, desktop for checkout
- Result: 40% increase in conversions!
