You mean Data Flow Diagram (DFD) ?
Ya I want data flow diagram with description.
Ill get some examples prepared but just some basics. A data flow diagram is used to show the flow of data in an information system. Some shapes:
Circle: represents a process. Basically the processes produce outgoing data flow from incoming data flow.
Arrow: represents the flow of the data between processes, data stores and external entities.
Rectangle: represents external entities, other groups or systems outside the current information system.
2 Parallel lines: represents a data store. Basically a process in which the storing of data takes place. (Archive, database) they can be manual, digital or temporary.
As for the rest ill produce an example and see if i have any sheets from class lying about ;)
Thanks for that.
This I know very well but I have to create a word document using the DFD.
I want some description about that ,I already make some DFD.
Thanks
I am confused you want a data flow diagram representing what?
I have to add those diagram in a word file with detail so I want to know about the best data flow description.
For that DFD you attached, explain what each entity is and how each process works. Did you also wish to know about some conventions in regards to DFD's? Well here they are anyway ;)
Every process must have atleast one data flow in and one data flow out.
Data should be transformed by the process.
External entities must be involved with atleast one data flow.
Data stores must be involved with atleast one data flow.
Data flow can not go directly from one external entity to another.
Yes I amQuote:
