The following are the details of the process documented through an exams handling information system.
(i)Candidate submits an official registration form for an examinations purpose at a definite or stated date including the examinations centre.
(ii)The exams clerk checks to ensure the exam is actually being held at a specified date and centre. Where there is doubt, the candidate receives back the registration form.
(iii)If it is okay, the exams clerk inputs the candidate’s particulars into the computer system. The system then automatically assigns the next accessible or available registration number to the registered candidate, and the last number allocated or assigned on the CANDIDATE-file-plus one.
(iv)The examinations clerk inputs the mandatory exams date and centre. The system assigns a seat number accordingly to that candidate for example (from the previous seat number and in that centre on a specified date-plus one).
(v)Candidate details (name, centre, number, examination date, address and seat number) are subsequently stored or kept on a CANDIDATE file. The details are printed out and then sent to the destination of the candidate.
Required:
(a)Construct a suitable process model (for example, a Data Flow Diagram, or Entity Relationship Diagram, or a flowchart) for the above business requirement.
(b)Provide the explanatory key to the model for the user to understand the notation.
(c)Pinpoint two questions the systems analyst should ask in order to improve the accuracy of your model. Explain the reason for asking eachof the questions.
Thanks a lot ❤
Community Edition needs more diagrams, like THIS one.
splendid ! thanks
I have decompose my big process into 2 process, but I forget to add a external entity. Then go to big process, add external entity, but It doesn't not sync, nothing new external entity in the decompose process. How I can refresh my decompose process?
Thank you
Community Edition doesn't have Data Flow Diagram. Which is the most important one
What jazz standard is this if I may ask?
I have to learn about these diagrams in my class. I don't even know why they are still a thing. Shouldn't UML be better for describing a system from a high level point of view? These diagrams feel so obsolete and limited. I mean, for some type of systems could work, but for object oriented, doesn't seem the right choice. What is your opinion?
why my new download visual paradigm, has no Data flow Diagram? what should I do.,,,because create Data flow Diagram is I need the most
thx ,great video
Which software you used to make this video?
VisualParadigm
The YT Channel's Name? :P
good
that's great and also wastage of time if you make diagram on visual paradigm because at the end you can not save
We do support saving the diagram even user is only using the free account. Would you please tell me more details about the problem you experienced?
Why the customer only received receipt and not the goods he ordered? :P
goods are not data flow
Why, receipt is a dataflow? It is like some principle of what customer get, out of letting go of his cash.
If goods aren't included, is money not included?
Jeffrey Catap think he means the dfd is for data, so the receipt is data which will be directed to the customer
Very well . Can you tell how to draw level 2
