3.3.2 BatchInteractiveReal-Time

Batch, interactive and real-time processing systems in terms of processing, response time and user interface requirements.

The user inputs data into the system when prompted to do so. Their actions are limited to what the system allows them to enter.

People queue waiting for the bus. When they get on, the driver asks where do they want to go? They pay their fare and the next person steps up!

Data is processed within a given maximum time limit (usually under 4 seconds). The time limit will depend on a number of factors: – User requirements – Type of processing – Amount to process

It is normally assumed that data will be processed as soon as it is received. This could result in data being updated straight away on a database, or an action taking place.

A good example of real-time processing is in auto-pilot systems. They wouldn’t be very useful in the following example…

Oh look, we’re heading towards that plane! I’ll save that information for later…
