“Our education system teaches us how to solve 200-year-old math problems but forgets to tell us how live apps like actually work.”
If you just stepped into college and feel clueless about tech terms being thrown around — welcome to reality. Let’s break down one such buzzword war: OLAP vs OLTP.
First Things First — WTF are OLAP and OLTP?
OLTP (Online Transaction Processing):
Imagine you are ordering momos from Zomato. You tap “Order Now”, payment happens, your order is saved, and the momo guy gets the notification. That small, fast transaction? That’s OLTP in action.
👉 OLTP = handles day-to-day operations.OLAP (Online Analytical Processing):
Now imagine Zomato wants to see “Which city eats the most momos at midnight?”. They don’t look at your single order. Instead, they analyze millions of orders to find patterns. That big, analytical brain? That’s OLAP.
👉 OLAP = handles analysis and insights.
Side-by-Side Breakdown
| Feature | OLTP (Transactional) | OLAP (Analytical) |
|---|---|---|
| Purpose | Running day-to-day apps (like payments, bookings, logins) | Analyzing data for decision-making |
| Data Size | Small transactions | Huge datasets |
| Speed | Fast reads/writes (milliseconds) | Complex queries (seconds/minutes) |
| Users | Frontline users (customers, employees) | Data analysts, managers |
| Example | Booking a cab on Ola | Ola analyzing busiest routes in Kolkata |
Why Should You Care?
Because everything around you runs on these systems.
- Your college’s “Online Result Portal” → OLTP
- The report your principal sees about “pass % of students over 5 years” → OLAP
- Instagram likes → OLTP
- Instagram showing which reels are trending in your city → OLAP
In short, OLTP = do things fast.
OLAP = think about things later.
