Problems in Data Processing
- Data Acquisition
It’s important for real-time systems.
V = Δx / Δt
- The speed of creating data
- The speed of storing data
- The speed of analyzing data => (Fast) Real-time processing
Late Decisions => Missing Opportunities 🙂
- Instantly capture
- Feed real-time to machine
- Process real-time
This process for business decisions
3. Variety [Size of data] = Complexity
The following items are heterogeneous.
Structed Variety – Semantic Variety
Media Variety – Availabilty
4. Verocity = Quality
- Accuracy of data
- Reliability of data source
Get the similarity with correlation.
Data connectivity: Two data items connected
Value = Velocity + Valance + Verocity + Volume + Variety
Also this is called diamond five.
