This overview of DFD's is more accurate and more clearly explained than 95% of what I see "experts" presenting on KZbin. Most of the DFD examples that are given in other videos are completely inaccurate, and rampant with Miracles (outputs with no inputs) or data stores initiating processes, sloppy thinking or other errors. You clearly walked through the process of decomposing the context level to level 1 of the DFD. I loved that you went through each incoming data flow, one by one, and defined your level 1 processes based on that. Simple but brilliant. Salamat !

In the 80’s I used a software to create the diagrams until the pseudo programming instructions it was on MSDOS. Do you know any software who do the whole process?

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
