How do real-time data extraction techniques differ from batch data extraction?
- Batch extraction is only suitable for small datasets
- Batch extraction processes data in predefined intervals
- Real-time extraction is less efficient than batch extraction
- Real-time extraction processes data immediately as it's generated
Real-time data extraction processes data immediately as it's generated, allowing for up-to-the-minute insights. In contrast, batch extraction collects and processes data in predefined intervals, introducing latency.
