Notes – Why Data Science is in Demand
In today’s digital world, every click, search, payment, or scroll generates data. But raw data alone is useless — companies need experts who can turn it into actionable insights. That’s where Data Science comes in.
1. Explosive Growth of Data
- Billions of devices, apps, and sensors generate data every second.
- From e-commerce to healthcare, companies are flooded with data.
- Businesses need Data Scientists to organize, analyze, and extract value from this information.
According to IDC, worldwide data is expected to grow to 175 zettabytes by 2025.
2. Data-Driven Decision Making
- Traditional decision-making based on guesswork is outdated.
- Today’s businesses rely on data-backed strategies to cut costs, increase sales, and improve customer experience.
