With a proper understanding of these variations, you will be well on your way to being able to create your own context diagram. Yet as with any good diagramming tool, there are also some notations to understand. That’s how a system context diagram represents a need for both brainstorming and diagramming tools.

In addition, they should help project stakeholders see the external factors and events to consider on top of the overall information system. These are all that are needed to show the interacting systems and the flow of data. There are three different core shapes to consider when creating a context diagram for the first time. Context Diagram Examples and How Data flow Diagrams are Broken Into 3 sectionsīefore we go into examples, we’re going to look at what a context diagram is comprised of. It’s meant to show the interior structure of a software system while also showing how external entities interact. The reason being is that the requirements document will need to dig deeper into the overall software system. It can sometimes appear on a requirements document, but there are other data flow diagrams for that. The most technical it gets is to show the data stores and the flow of data. This means that this type of data flow diagram (DFD) can work with any type of system. Creating a context diagram means creating data flow diagrams at that level 0 or high-level overview. Data flow diagrams come in different levels of complexity. But remember that it’s at level 0, meaning no technical knowledge is required. Well for a start, a system context diagram represents any type of system. But what are some context diagram examples? These external factors and events help show the flow of data between interacting systems. It has to show how external entities interact with the software system. Its purpose is to have easy absorption by project stakeholders, and you can use it in conjunction with a business mind map. Yet it does so on a high level with the idea that you require minimal to no technical knowledge. When it comes to data flow diagrams, a context diagram shows how a system works.
