Your individual task for this stage is to research and read more about Data Flow Diagrams (DFD).
Use the resource link below for examples and guidance
http://www.sqa.org.uk/e-learning/SDM03CD/page_07.htm
As an individual, you will develop an outline of any unique statements (situation) different from the examples in the link above and develop a DFD diagram to model the situation outlined above. i.e Red Dragon Company situation.
Design Assessment Rubric

Descriptors
|
0
|
The design does not meet the standards of the descriptors shown below.
|
1-3
|
The design shows limited development of instructions statements (situation) thus not suitable for the development of the DFD. The DFD structure developed is not detailed, not logical and uses limited standard DFD symbols in it’s presentation. Limited processes are used to show the flow of data in the system of choice.
|
4-6
|
The design developed shows some good instructions statements (situation) that can be used to develop a good DFD. The DFD structure developed is detailed, logical and uses a range of DFD symbols in its design. Some important processes are used to show the flow of data in the system of choice.
|
7-8
|
The design shows that most of instruction statements are comprehensive thus useful in developing a thorough DFD structure. The DFD structure developed is comprehensive, detailed, logical and uses a variety of standard DFD symbols appropriately. Several important processes are used to show the flow of data in the system of choice in a comprehensive way.
