2a- Types of Processing
- Batch
- All processing done at once
when servers aren't as busy.
- Don't usually need
user interface
- Necessary data already input into
the system before processing
- Uses a template (master file) where data is
put on (transition file) to have a set format
for entering data into or out of the system.
- X - Set processing time means
delayed response and can lead to
long wait for output.
- E.g. Processing monthly
bills by a company
- Interactive
- User communicates and works with
computer by inputting data and
getting an output.
- Computer responds as fast as it can process
- Data stored in RAM during processing
- Usually uses graphical user interface (GUI)
- e.g. Database Query
- Real Time
- Data is processed immediately
using data matching the real world.
- Batch or interactive
- Very quick processing
- Interface may vary depending
on user requirement
- e.g. Central heating system
heats or cools immediately
based on temperature of room
- e.g. Plane ticket booking
system immediately updates
when ticket is sold.
