Data flow - Process
Stream processing
Software processing each new piece of data as soon as it is received
What's it for?
Processes information continuously as it arrives when waiting for a later batch would be too slow.
For example…
Fraud checks score each card payment within seconds rather than waiting for end-of-day files.
A fraud system uses stream processing to score each card transaction as it arrives instead of waiting for a nightly batch
Think of it like…
Conveyor belt inspected as items pass, not a pile sorted once a day
