Data Flow Diagram With Examples
This article describes and explains about Data Flow Diagram with Examples that will give you a detailed idea of what is Data Flow Diagram and How to Create a Data Flow Diagram with Examples.
What is Data Flow Diagram?
A Data Flow Diagram or (DFD) is a way of visual representation of a flow of data in a certain process or system. The data flow diagram can provide information about the process, inputs, and outputs of each entity.
The data flow diagram uses defined symbols like rectangles, circles, and arrows, plus short text labels, to show data inputs, outputs, storage points and the routes between each destination.
A data flow diagram has no decision, loops, and control flow.

Data Flow Diagram With Examples
- Library Borrowing System Data Flow Diagram Example
In this Library Borrowing System Dataflow Digram example the librarian will log in to the system and then the librarian will register students and books that are in the library. If the students have been registered and wanted to borrow books, the student will search the book/s, and then he/she will present his/her registered library card together with the book/s he/she intended to borrow. The librarian will record the transaction using the proposed system and will set the due date for the book to be returned.

When the student returned the book before the due date, the staff will record the transaction successfully and update the booking status. In case of loss or damage, the librarian will give a fine to the student that will be given to the accounting office for penalty purposes.
- Sales and Inventory System Data Flow Diagram Example
In this Sales and Inventory System data flow Diagram Example, you can see there the process of data from Customer order to Point of Sale with the help of cashier for processing of order requested by a specific customer.
