Software Design and Development: Analysis

What is meant by purpose in relation to software?

• How the user uses the software.

• What the software is to do eg calculate the best route to a specified destination.

• A clear statement of exactly what the problem is that needs to be solved.

• The person or organisation that the software is being created for.

During the analysis stage, the programmer(s) will meet up with the client to help work out exactly what is required. What is a client?

• The person who will program the software.

• The device that the software will be created on.

• The person, company or organisation who the software is being developed for.

• The person, or people, who will end up using the software but did not commission it eg game players.

What is the software specification?

• A clear statement of exactly what the problem is that needs to be solved.

• What the software is to do eg calculate the best route to a specified destination.

• The person, or people, who will end up using the software but did not commission it eg game players.

• The device that the software will be run on.

What is meant by functional requirements?

• The device that the software will be run on.

• The processes that the software must be able to carry out.

• A clear statement of exactly what the problem is that needs to be solved.

• The person who will program the software.

What three elements are functional requirements broken down into?

• Functions, formulae and results.

• Inputs, processes and outputs.

• Input devices, central processing unit (CPU) and output devices.

• Algorithms, arithmetic operators and flow charts.

What is an input?

• The processing of the data eg calculating an answer.

• A device used to enter data into a processing device.

• Data that comes out of the device eg displayed on a monitor.

• Data that is entered by the user eg using a keyboard.

What is an output?

• The processing of the data eg calculating an answer.

• A device used to enter data into a processing device.

• Information that comes out of the device eg displayed on a monitor.

• Data that is entered by the user eg using a keyboard.

What is a process?

• The processing of the data eg calculating an answer.

• A device used to enter data into a processing device.

• Information that comes out of the device eg displayed on a monitor.

• Data that is entered by the user eg using a keyboard.
