Flowcharts and Data Flow Diagrams (DFD’s) explained

4 Feb

Hi all, in my first post I will explain Flowcharts and Data Flow Diagrams at a basic level. Flowcharts help businesses assess their data. A Flowchart can also display a step by step analysis of a business model. This in turn helps show valuable information to employees, managers and shareholders in the business in a simpler way. Flowcharts are used in presentations. There are many shapes/actions in each Flowchart. There are many different types of Flow Charts. The contents of each flowchart depends on its purpose e.g a business flowchart will show how the business is performing.

This is an example of a flowchart of a Small Business start-up


This is an example of a Flowchart with making a friend. This is an easier graph to understand and shows the way the decisions in the flowchart affects the final outcome.



I hope that made it easier for everyone to understand Flowcharts at a more basic level, now I will talk about Data Flow Diagrams.Data Flow Diagrams shows the flow of Data internally and externally. DFD’s are mostly used in the computer industry’s. DFD’s are a graphical way of showing how a business is run.

Below is a simple version of a Data Flow Diagram


Data flow charts are similar to flowcharts but have a few key differences which I will discuss the next week.
