wow mind blowing video, breaking all the rules of DFD. What's wrong with youtubers today, even they themselves don't know anything and they are teaching us.

the process should be in circle shape ! we cannot draw data flows from one entity to different entity
@dharminshah27226 жыл бұрын
The airline reservation system should be enclosed within a circle as it is a process and not an entity.

🎯 Key Takeaways for quick navigation: 00:00 📊 Introduction to Data Flow Diagrams - Data flow diagrams (DFD) are graphical representations of data flow within a system. - DFDs highlight how a system is divided into smaller portions and illustrate the flow of data between these parts. 02:10 🧩 DFD Symbols - DFD symbols include squares (representing sources or destinations of data), arrows (identifying data flow), circles/bubbles (depicting processes), and open rectangles (indicating data stores). - Squares denote where data originates or is sent, arrows signify data flow direction, circles/bubbles represent processes, and open rectangles denote data at rest. 06:33 🏗️ Constructing a DFD Example - An example of constructing a DFD for an airline reservation system is shown, with squares representing sources and destinations. - The data flow is illustrated as it moves from the passenger to the airline reservation system, through the travel agent, and eventually to the airlines, showing the flow of information.

Airline reservation system should be in circle. For your kind information you are breaking rules of the data flow diagram. If you don't know about the chapter then don't teach student wrong 🙏

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
