How to create a Level-1 Data Flow Diagram (DFD)

[@sundayagu2078]

Great job. Just to the point flowing from the previous video. Many thanks

[@floofzykitty5072]

It seems like there is nothing everyone can agree on when it comes to level 1 DFD. In my syllabus, external entities are not allowed to be shown in level 1 DFD, only processes and data stores, and different sources seem to have different ways of constructing them.

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. Please help me out

Hello Degan. Thanks for your efforts. Can I use DFD to implement an SDN Network Management System? The developed management system handles topology modeling, load balancing, security, and routing. Thanks in advance.

[@ame1783]

how about that process 1? the process goes to the datastore but the datastore never output the data. that is not allowed as far as i know

[@freemason3387]

There are seems to be many different versions of DFD on the internet, dunno who is right or standard. To me, the DFD sometimes looks a bit confusing. Some even say the DFD is outdated.
