Tuck
Shop
A
program that’s stores information/records in a spreadsheet (Similar to
Microsoft Excel) for a period of time. It could also change a data if the data
changes in real life. EX. A supermarket, a school supply shop, etc
Traffic
Light simulator
It
simulate a scenario about traffic light. It simulate with the data gather,
either manually or by a computer.
Information
gathers:
·
How many cars pass in a weekday, weekend or holiday.
·
Direction cars go to
·
Time taking for a average car to finish the junction
·
Time taken for the slowest car
·
How pedestrian crossing over effect the traffic
The
profit for this is :
ü
No risk when trying out scenario
ü
Testing all scenario takes less time
ü
Expenses for testing the scenario is cheaper
Simulations
are used because it is less expensive than building the real thing.
Architectural simulation
Architectural simulation is a simulation on buildings. This is to test if the building could
hold and what is its limitation. The information needed is basic physics and
what material will the building use.
Just
like the traffic light simulation, it is safer, cheaper and faster if you
simulate this than testing it in real life. It could even simulate if the
building will get damaged in certain weather.
3 Types of Processing:
1.
Batch processing
2.
Real Time(transaction) or online processing
3.
Real time process control
Batch
processing is the execution of a series of programs on a computer without
manual intervention. It is often use in Banks, Billing System and Payroll
system. It doesn't need to update manually, it will update automatically, when
the system is less busy (e.g. overnight when people are less active). It will
update its main server and it will do it
frequently.
Real-Time
(Transaction) or online processing
It
is an example of Online processing, and it could be used in Theatre, ATM,
flight and etc. Unlike the Batch processing, this will have to be faster, to
prevent 'double booking'. It will update as fast as possible to its main
server. This process has a time lag and isn't instantly updated
Real-Time
Process Control
Real-time
Process Control is instant process. There is no time lag. It is also an example
of online processing. It is used in games, where is needs no lag when playing.
It is also used when measuring physical quantities.
